Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588262, here are decompositions:
- 61 + 31588201 = 31588262
- 283 + 31587979 = 31588262
- 313 + 31587949 = 31588262
- 463 + 31587799 = 31588262
- 829 + 31587433 = 31588262
- 991 + 31587271 = 31588262
- 1039 + 31587223 = 31588262
- 1171 + 31587091 = 31588262
Showing the first eight; more decompositions exist.
