Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5518, here are decompositions:

11 + 5507 = 5518
17 + 5501 = 5518
41 + 5477 = 5518
47 + 5471 = 5518
101 + 5417 = 5518
131 + 5387 = 5518
137 + 5381 = 5518
167 + 5351 = 5518

Showing the first eight; more decompositions exist.
