Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588200, here are decompositions:
- 29 + 31588171 = 31588200
- 43 + 31588157 = 31588200
- 71 + 31588129 = 31588200
- 97 + 31588103 = 31588200
- 113 + 31588087 = 31588200
- 139 + 31588061 = 31588200
- 181 + 31588019 = 31588200
- 197 + 31588003 = 31588200
Showing the first eight; more decompositions exist.
