Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105672, here are decompositions:
- 5 + 105667 = 105672
- 19 + 105653 = 105672
- 23 + 105649 = 105672
- 53 + 105619 = 105672
- 59 + 105613 = 105672
- 71 + 105601 = 105672
- 109 + 105563 = 105672
- 131 + 105541 = 105672
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 105,672 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
