Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494338, here are decompositions:
- 37 + 31494301 = 31494338
- 97 + 31494241 = 31494338
- 181 + 31494157 = 31494338
- 241 + 31494097 = 31494338
- 349 + 31493989 = 31494338
- 397 + 31493941 = 31494338
- 439 + 31493899 = 31494338
- 457 + 31493881 = 31494338
Showing the first eight; more decompositions exist.
