Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101518, here are decompositions:

5 + 101513 = 101518
17 + 101501 = 101518
29 + 101489 = 101518
41 + 101477 = 101518
89 + 101429 = 101518
107 + 101411 = 101518
239 + 101279 = 101518
251 + 101267 = 101518

Showing the first eight; more decompositions exist.
