Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615310, here are decompositions:
- 37 + 31615273 = 31615310
- 73 + 31615237 = 31615310
- 157 + 31615153 = 31615310
- 271 + 31615039 = 31615310
- 367 + 31614943 = 31615310
- 421 + 31614889 = 31615310
- 457 + 31614853 = 31615310
- 523 + 31614787 = 31615310
Showing the first eight; more decompositions exist.
