Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578740, here are decompositions:

  • 11 + 578729 = 578740
  • 47 + 578693 = 578740
  • 53 + 578687 = 578740
  • 131 + 578609 = 578740
  • 137 + 578603 = 578740
  • 167 + 578573 = 578740
  • 251 + 578489 = 578740
  • 257 + 578483 = 578740

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 578,740 and was likely granted around 1896.

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

Position in π

The digit sequence 578740 first appears in π at position 290,055 of the decimal expansion (the 290,055ordinal-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.
