Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473750, here are decompositions:
- 17 + 31473733 = 31473750
- 43 + 31473707 = 31473750
- 47 + 31473703 = 31473750
- 151 + 31473599 = 31473750
- 157 + 31473593 = 31473750
- 167 + 31473583 = 31473750
- 227 + 31473523 = 31473750
- 263 + 31473487 = 31473750
Showing the first eight; more decompositions exist.
