Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7520, here are decompositions:

3 + 7517 = 7520
13 + 7507 = 7520
31 + 7489 = 7520
43 + 7477 = 7520
61 + 7459 = 7520
103 + 7417 = 7520
109 + 7411 = 7520
127 + 7393 = 7520

Showing the first eight; more decompositions exist.
