Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512242, here are decompositions:

  • 149 + 512093 = 512242
  • 233 + 512009 = 512242
  • 251 + 511991 = 512242
  • 281 + 511961 = 512242
  • 383 + 511859 = 512242
  • 431 + 511811 = 512242
  • 449 + 511793 = 512242
  • 659 + 511583 = 512242

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 512,242 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 512242 first appears in π at position 194,223 of the decimal expansion (the 194,223ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
