Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474814, here are decompositions:
- 13 + 31474801 = 31474814
- 31 + 31474783 = 31474814
- 37 + 31474777 = 31474814
- 67 + 31474747 = 31474814
- 127 + 31474687 = 31474814
- 313 + 31474501 = 31474814
- 457 + 31474357 = 31474814
- 463 + 31474351 = 31474814
Showing the first eight; more decompositions exist.
