Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493952, here are decompositions:
- 11 + 31493941 = 31493952
- 43 + 31493909 = 31493952
- 53 + 31493899 = 31493952
- 71 + 31493881 = 31493952
- 101 + 31493851 = 31493952
- 131 + 31493821 = 31493952
- 163 + 31493789 = 31493952
- 173 + 31493779 = 31493952
Showing the first eight; more decompositions exist.
