Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5240, here are decompositions:

3 + 5237 = 5240
7 + 5233 = 5240
13 + 5227 = 5240
31 + 5209 = 5240
43 + 5197 = 5240
61 + 5179 = 5240
73 + 5167 = 5240
127 + 5113 = 5240

Showing the first eight; more decompositions exist.
