Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522480, here are decompositions:
- 29 + 31522451 = 31522480
- 47 + 31522433 = 31522480
- 107 + 31522373 = 31522480
- 149 + 31522331 = 31522480
- 167 + 31522313 = 31522480
- 233 + 31522247 = 31522480
- 239 + 31522241 = 31522480
- 251 + 31522229 = 31522480
Showing the first eight; more decompositions exist.
