Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130518, here are decompositions:

5 + 130513 = 130518
29 + 130489 = 130518
41 + 130477 = 130518
61 + 130457 = 130518
71 + 130447 = 130518
79 + 130439 = 130518
107 + 130411 = 130518
109 + 130409 = 130518

Showing the first eight; more decompositions exist.
