Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5540, here are decompositions:

13 + 5527 = 5540
19 + 5521 = 5540
37 + 5503 = 5540
61 + 5479 = 5540
97 + 5443 = 5540
103 + 5437 = 5540
109 + 5431 = 5540
127 + 5413 = 5540

Showing the first eight; more decompositions exist.
