Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474790, here are decompositions:
- 7 + 31474783 = 31474790
- 13 + 31474777 = 31474790
- 43 + 31474747 = 31474790
- 97 + 31474693 = 31474790
- 103 + 31474687 = 31474790
- 241 + 31474549 = 31474790
- 271 + 31474519 = 31474790
- 367 + 31474423 = 31474790
Showing the first eight; more decompositions exist.
