Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167628, here are decompositions:
- 5 + 167623 = 167628
- 7 + 167621 = 167628
- 17 + 167611 = 167628
- 31 + 167597 = 167628
- 107 + 167521 = 167628
- 137 + 167491 = 167628
- 157 + 167471 = 167628
- 179 + 167449 = 167628
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 167,628 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 167628 first appears in π at position 530,442 of the decimal expansion (the 530,442ordinal-suffix:nd 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.
