Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493126, here are decompositions:
- 43 + 31493083 = 31493126
- 73 + 31493053 = 31493126
- 79 + 31493047 = 31493126
- 97 + 31493029 = 31493126
- 109 + 31493017 = 31493126
- 163 + 31492963 = 31493126
- 193 + 31492933 = 31493126
- 277 + 31492849 = 31493126
Showing the first eight; more decompositions exist.
