Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49990, here are decompositions:
- 47 + 49943 = 49990
- 53 + 49937 = 49990
- 71 + 49919 = 49990
- 113 + 49877 = 49990
- 137 + 49853 = 49990
- 167 + 49823 = 49990
- 179 + 49811 = 49990
- 233 + 49757 = 49990
Showing the first eight; more decompositions exist.
