Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522536, here are decompositions:
- 7 + 31522529 = 31522536
- 13 + 31522523 = 31522536
- 43 + 31522493 = 31522536
- 103 + 31522433 = 31522536
- 163 + 31522373 = 31522536
- 173 + 31522363 = 31522536
- 179 + 31522357 = 31522536
- 197 + 31522339 = 31522536
Showing the first eight; more decompositions exist.
