Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615584, here are decompositions:
- 41 + 31615543 = 31615584
- 101 + 31615483 = 31615584
- 107 + 31615477 = 31615584
- 113 + 31615471 = 31615584
- 167 + 31615417 = 31615584
- 181 + 31615403 = 31615584
- 193 + 31615391 = 31615584
- 241 + 31615343 = 31615584
Showing the first eight; more decompositions exist.
