Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000172, here are decompositions:
- 13 + 1000159 = 1000172
- 73 + 1000099 = 1000172
- 139 + 1000033 = 1000172
- 193 + 999979 = 1000172
- 211 + 999961 = 1000172
- 241 + 999931 = 1000172
- 409 + 999763 = 1000172
- 541 + 999631 = 1000172
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 1,000,172 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
