Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542316, here are decompositions:
- 83 + 31542233 = 31542316
- 167 + 31542149 = 31542316
- 233 + 31542083 = 31542316
- 293 + 31542023 = 31542316
- 383 + 31541933 = 31542316
- 683 + 31541633 = 31542316
- 719 + 31541597 = 31542316
- 809 + 31541507 = 31542316
Showing the first eight; more decompositions exist.
