Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624718, here are decompositions:
- 19 + 31624699 = 31624718
- 79 + 31624639 = 31624718
- 127 + 31624591 = 31624718
- 211 + 31624507 = 31624718
- 241 + 31624477 = 31624718
- 331 + 31624387 = 31624718
- 379 + 31624339 = 31624718
- 397 + 31624321 = 31624718
Showing the first eight; more decompositions exist.
