Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49638, here are decompositions:
- 5 + 49633 = 49638
- 11 + 49627 = 49638
- 41 + 49597 = 49638
- 79 + 49559 = 49638
- 89 + 49549 = 49638
- 101 + 49537 = 49638
- 107 + 49531 = 49638
- 109 + 49529 = 49638
Showing the first eight; more decompositions exist.
