Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49840, here are decompositions:

17 + 49823 = 49840
29 + 49811 = 49840
53 + 49787 = 49840
83 + 49757 = 49840
101 + 49739 = 49840
113 + 49727 = 49840
173 + 49667 = 49840
227 + 49613 = 49840

Showing the first eight; more decompositions exist.
