Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539244, here are decompositions:
- 3 + 31539241 = 31539244
- 53 + 31539191 = 31539244
- 101 + 31539143 = 31539244
- 197 + 31539047 = 31539244
- 257 + 31538987 = 31539244
- 293 + 31538951 = 31539244
- 491 + 31538753 = 31539244
- 683 + 31538561 = 31539244
Showing the first eight; more decompositions exist.
