Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49878, here are decompositions:
- 7 + 49871 = 49878
- 47 + 49831 = 49878
- 67 + 49811 = 49878
- 71 + 49807 = 49878
- 89 + 49789 = 49878
- 131 + 49747 = 49878
- 137 + 49741 = 49878
- 139 + 49739 = 49878
Showing the first eight; more decompositions exist.
