Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493750, here are decompositions:
- 7 + 31493743 = 31493750
- 61 + 31493689 = 31493750
- 73 + 31493677 = 31493750
- 97 + 31493653 = 31493750
- 109 + 31493641 = 31493750
- 139 + 31493611 = 31493750
- 151 + 31493599 = 31493750
- 157 + 31493593 = 31493750
Showing the first eight; more decompositions exist.
