Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615124, here are decompositions:
- 61 + 31615063 = 31615124
- 181 + 31614943 = 31615124
- 271 + 31614853 = 31615124
- 337 + 31614787 = 31615124
- 421 + 31614703 = 31615124
- 523 + 31614601 = 31615124
- 577 + 31614547 = 31615124
- 601 + 31614523 = 31615124
Showing the first eight; more decompositions exist.
