Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006940, here are decompositions:
- 3 + 1006937 = 1006940
- 7 + 1006933 = 1006940
- 43 + 1006897 = 1006940
- 61 + 1006879 = 1006940
- 79 + 1006861 = 1006940
- 157 + 1006783 = 1006940
- 229 + 1006711 = 1006940
- 307 + 1006633 = 1006940
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 1,006,940 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
