Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475750, here are decompositions:
- 37 + 31475713 = 31475750
- 67 + 31475683 = 31475750
- 73 + 31475677 = 31475750
- 127 + 31475623 = 31475750
- 139 + 31475611 = 31475750
- 151 + 31475599 = 31475750
- 307 + 31475443 = 31475750
- 349 + 31475401 = 31475750
Showing the first eight; more decompositions exist.
