Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479608, here are decompositions:
- 19 + 31479589 = 31479608
- 31 + 31479577 = 31479608
- 67 + 31479541 = 31479608
- 109 + 31479499 = 31479608
- 151 + 31479457 = 31479608
- 271 + 31479337 = 31479608
- 331 + 31479277 = 31479608
- 337 + 31479271 = 31479608
Showing the first eight; more decompositions exist.
