Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531032, here are decompositions:
- 31 + 31531001 = 31531032
- 53 + 31530979 = 31531032
- 59 + 31530973 = 31531032
- 73 + 31530959 = 31531032
- 89 + 31530943 = 31531032
- 131 + 31530901 = 31531032
- 139 + 31530893 = 31531032
- 191 + 31530841 = 31531032
Showing the first eight; more decompositions exist.
