Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522440, here are decompositions:
- 7 + 31522433 = 31522440
- 29 + 31522411 = 31522440
- 67 + 31522373 = 31522440
- 83 + 31522357 = 31522440
- 101 + 31522339 = 31522440
- 109 + 31522331 = 31522440
- 113 + 31522327 = 31522440
- 127 + 31522313 = 31522440
Showing the first eight; more decompositions exist.
