Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508482, here are decompositions:
- 29 + 31508453 = 31508482
- 251 + 31508231 = 31508482
- 311 + 31508171 = 31508482
- 389 + 31508093 = 31508482
- 443 + 31508039 = 31508482
- 479 + 31508003 = 31508482
- 491 + 31507991 = 31508482
- 569 + 31507913 = 31508482
Showing the first eight; more decompositions exist.
