Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523736, here are decompositions:
- 29 + 31523707 = 31523736
- 67 + 31523669 = 31523736
- 89 + 31523647 = 31523736
- 103 + 31523633 = 31523736
- 137 + 31523599 = 31523736
- 157 + 31523579 = 31523736
- 197 + 31523539 = 31523736
- 199 + 31523537 = 31523736
Showing the first eight; more decompositions exist.
