Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56240, here are decompositions:

3 + 56237 = 56240
31 + 56209 = 56240
43 + 56197 = 56240
61 + 56179 = 56240
73 + 56167 = 56240
109 + 56131 = 56240
127 + 56113 = 56240
139 + 56101 = 56240

Showing the first eight; more decompositions exist.
