Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49820, here are decompositions:
- 13 + 49807 = 49820
- 19 + 49801 = 49820
- 31 + 49789 = 49820
- 37 + 49783 = 49820
- 73 + 49747 = 49820
- 79 + 49741 = 49820
- 109 + 49711 = 49820
- 139 + 49681 = 49820
Showing the first eight; more decompositions exist.
