Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162672, here are decompositions:
- 23 + 162649 = 162672
- 31 + 162641 = 162672
- 43 + 162629 = 162672
- 61 + 162611 = 162672
- 71 + 162601 = 162672
- 79 + 162593 = 162672
- 109 + 162563 = 162672
- 149 + 162523 = 162672
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 162,672 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 162672 first appears in π at position 994,573 of the decimal expansion (the 994,573ordinal-suffix:rd 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.
