Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49890, here are decompositions:
- 13 + 49877 = 49890
- 19 + 49871 = 49890
- 37 + 49853 = 49890
- 47 + 49843 = 49890
- 59 + 49831 = 49890
- 67 + 49823 = 49890
- 79 + 49811 = 49890
- 83 + 49807 = 49890
Showing the first eight; more decompositions exist.
