Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123718, here are decompositions:
- 11 + 123707 = 123718
- 17 + 123701 = 123718
- 41 + 123677 = 123718
- 137 + 123581 = 123718
- 167 + 123551 = 123718
- 191 + 123527 = 123718
- 227 + 123491 = 123718
- 239 + 123479 = 123718
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 123,718 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123718 first appears in π at position 2,938 of the decimal expansion (the 2,938ordinal-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.
