Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448736, here are decompositions:
- 17 + 31448719 = 31448736
- 19 + 31448717 = 31448736
- 23 + 31448713 = 31448736
- 29 + 31448707 = 31448736
- 37 + 31448699 = 31448736
- 43 + 31448693 = 31448736
- 89 + 31448647 = 31448736
- 97 + 31448639 = 31448736
Showing the first eight; more decompositions exist.
