Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615718, here are decompositions:
- 7 + 31615711 = 31615718
- 67 + 31615651 = 31615718
- 109 + 31615609 = 31615718
- 229 + 31615489 = 31615718
- 241 + 31615477 = 31615718
- 397 + 31615321 = 31615718
- 829 + 31614889 = 31615718
- 859 + 31614859 = 31615718
Showing the first eight; more decompositions exist.
