Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474754, here are decompositions:
- 7 + 31474747 = 31474754
- 61 + 31474693 = 31474754
- 67 + 31474687 = 31474754
- 331 + 31474423 = 31474754
- 397 + 31474357 = 31474754
- 463 + 31474291 = 31474754
- 541 + 31474213 = 31474754
- 613 + 31474141 = 31474754
Showing the first eight; more decompositions exist.
