Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615316, here are decompositions:
- 3 + 31615313 = 31615316
- 43 + 31615273 = 31615316
- 79 + 31615237 = 31615316
- 163 + 31615153 = 31615316
- 277 + 31615039 = 31615316
- 373 + 31614943 = 31615316
- 457 + 31614859 = 31615316
- 463 + 31614853 = 31615316
Showing the first eight; more decompositions exist.
