Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529736, here are decompositions:
- 19 + 31529717 = 31529736
- 59 + 31529677 = 31529736
- 67 + 31529669 = 31529736
- 107 + 31529629 = 31529736
- 113 + 31529623 = 31529736
- 179 + 31529557 = 31529736
- 197 + 31529539 = 31529736
- 229 + 31529507 = 31529736
Showing the first eight; more decompositions exist.
