Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474736, here are decompositions:
- 3 + 31474733 = 31474736
- 43 + 31474693 = 31474736
- 67 + 31474669 = 31474736
- 313 + 31474423 = 31474736
- 373 + 31474363 = 31474736
- 379 + 31474357 = 31474736
- 487 + 31474249 = 31474736
- 523 + 31474213 = 31474736
Showing the first eight; more decompositions exist.
