Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588976, here are decompositions:
- 19 + 31588957 = 31588976
- 43 + 31588933 = 31588976
- 79 + 31588897 = 31588976
- 163 + 31588813 = 31588976
- 277 + 31588699 = 31588976
- 283 + 31588693 = 31588976
- 373 + 31588603 = 31588976
- 577 + 31588399 = 31588976
Showing the first eight; more decompositions exist.
