Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522216, here are decompositions:
- 113 + 31522103 = 31522216
- 197 + 31522019 = 31522216
- 239 + 31521977 = 31522216
- 263 + 31521953 = 31522216
- 353 + 31521863 = 31522216
- 503 + 31521713 = 31522216
- 569 + 31521647 = 31522216
- 617 + 31521599 = 31522216
Showing the first eight; more decompositions exist.
