Goldbach decomposition

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.
