Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494032, here are decompositions:
- 43 + 31493989 = 31494032
- 151 + 31493881 = 31494032
- 181 + 31493851 = 31494032
- 211 + 31493821 = 31494032
- 379 + 31493653 = 31494032
- 421 + 31493611 = 31494032
- 433 + 31493599 = 31494032
- 439 + 31493593 = 31494032
Showing the first eight; more decompositions exist.
