Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474910, here are decompositions:
- 37 + 31474873 = 31474910
- 43 + 31474867 = 31474910
- 109 + 31474801 = 31474910
- 127 + 31474783 = 31474910
- 163 + 31474747 = 31474910
- 223 + 31474687 = 31474910
- 241 + 31474669 = 31474910
- 409 + 31474501 = 31474910
Showing the first eight; more decompositions exist.
