Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168624, here are decompositions:
- 7 + 168617 = 168624
- 23 + 168601 = 168624
- 83 + 168541 = 168624
- 97 + 168527 = 168624
- 101 + 168523 = 168624
- 167 + 168457 = 168624
- 173 + 168451 = 168624
- 191 + 168433 = 168624
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 168,624 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 168624 first appears in π at position 840,464 of the decimal expansion (the 840,464ordinal-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.
