Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522304, here are decompositions:
- 7 + 31522297 = 31522304
- 61 + 31522243 = 31522304
- 97 + 31522207 = 31522304
- 283 + 31522021 = 31522304
- 313 + 31521991 = 31522304
- 421 + 31521883 = 31522304
- 631 + 31521673 = 31522304
- 661 + 31521643 = 31522304
Showing the first eight; more decompositions exist.
