Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720496, here are decompositions:
- 7 + 8720489 = 8720496
- 13 + 8720483 = 8720496
- 17 + 8720479 = 8720496
- 19 + 8720477 = 8720496
- 67 + 8720429 = 8720496
- 79 + 8720417 = 8720496
- 89 + 8720407 = 8720496
- 107 + 8720389 = 8720496
Showing the first eight; more decompositions exist.
