Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001172, here are decompositions:
- 13 + 1001159 = 1001172
- 19 + 1001153 = 1001172
- 79 + 1001093 = 1001172
- 83 + 1001089 = 1001172
- 103 + 1001069 = 1001172
- 131 + 1001041 = 1001172
- 149 + 1001023 = 1001172
- 173 + 1000999 = 1001172
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 1,001,172 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
