Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525242, here are decompositions:
- 13 + 31525229 = 31525242
- 29 + 31525213 = 31525242
- 31 + 31525211 = 31525242
- 41 + 31525201 = 31525242
- 59 + 31525183 = 31525242
- 79 + 31525163 = 31525242
- 139 + 31525103 = 31525242
- 211 + 31525031 = 31525242
Showing the first eight; more decompositions exist.
