Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594490, here are decompositions:
- 61 + 31594429 = 31594490
- 97 + 31594393 = 31594490
- 139 + 31594351 = 31594490
- 157 + 31594333 = 31594490
- 181 + 31594309 = 31594490
- 331 + 31594159 = 31594490
- 409 + 31594081 = 31594490
- 547 + 31593943 = 31594490
Showing the first eight; more decompositions exist.
