Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515152, here are decompositions:

  • 3 + 515149 = 515152
  • 41 + 515111 = 515152
  • 263 + 514889 = 515152
  • 293 + 514859 = 515152
  • 311 + 514841 = 515152
  • 359 + 514793 = 515152
  • 383 + 514769 = 515152
  • 401 + 514751 = 515152

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 515,152 and was likely granted around 1894.

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

Position in π

The digit sequence 515152 first appears in π at position 364,899 of the decimal expansion (the 364,899ordinal-suffix:th 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.
