Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508732, here are decompositions:
- 19 + 31508713 = 31508732
- 61 + 31508671 = 31508732
- 163 + 31508569 = 31508732
- 223 + 31508509 = 31508732
- 271 + 31508461 = 31508732
- 373 + 31508359 = 31508732
- 421 + 31508311 = 31508732
- 499 + 31508233 = 31508732
Showing the first eight; more decompositions exist.
