Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588370, here are decompositions:
- 3 + 31588367 = 31588370
- 13 + 31588357 = 31588370
- 19 + 31588351 = 31588370
- 67 + 31588303 = 31588370
- 103 + 31588267 = 31588370
- 199 + 31588171 = 31588370
- 241 + 31588129 = 31588370
- 283 + 31588087 = 31588370
Showing the first eight; more decompositions exist.
