Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497812, here are decompositions:
- 61 + 31497751 = 31497812
- 139 + 31497673 = 31497812
- 211 + 31497601 = 31497812
- 271 + 31497541 = 31497812
- 349 + 31497463 = 31497812
- 421 + 31497391 = 31497812
- 499 + 31497313 = 31497812
- 673 + 31497139 = 31497812
Showing the first eight; more decompositions exist.
