Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103518, here are decompositions:

7 + 103511 = 103518
47 + 103471 = 103518
61 + 103457 = 103518
67 + 103451 = 103518
97 + 103421 = 103518
109 + 103409 = 103518
127 + 103391 = 103518
131 + 103387 = 103518

Showing the first eight; more decompositions exist.
