Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49040, here are decompositions:

3 + 49037 = 49040
7 + 49033 = 49040
31 + 49009 = 49040
37 + 49003 = 49040
67 + 48973 = 49040
151 + 48889 = 49040
157 + 48883 = 49040
181 + 48859 = 49040

Showing the first eight; more decompositions exist.
