Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49640, here are decompositions:
- 7 + 49633 = 49640
- 13 + 49627 = 49640
- 37 + 49603 = 49640
- 43 + 49597 = 49640
- 103 + 49537 = 49640
- 109 + 49531 = 49640
- 163 + 49477 = 49640
- 181 + 49459 = 49640
Showing the first eight; more decompositions exist.
