Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522420, here are decompositions:
- 47 + 31522373 = 31522420
- 89 + 31522331 = 31522420
- 107 + 31522313 = 31522420
- 173 + 31522247 = 31522420
- 179 + 31522241 = 31522420
- 191 + 31522229 = 31522420
- 239 + 31522181 = 31522420
- 317 + 31522103 = 31522420
Showing the first eight; more decompositions exist.
