Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494044, here are decompositions:
- 3 + 31494041 = 31494044
- 61 + 31493983 = 31494044
- 103 + 31493941 = 31494044
- 163 + 31493881 = 31494044
- 193 + 31493851 = 31494044
- 223 + 31493821 = 31494044
- 367 + 31493677 = 31494044
- 433 + 31493611 = 31494044
Showing the first eight; more decompositions exist.
