Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130718, here are decompositions:

19 + 130699 = 130718
31 + 130687 = 130718
37 + 130681 = 130718
61 + 130657 = 130718
67 + 130651 = 130718
79 + 130639 = 130718
97 + 130621 = 130718
139 + 130579 = 130718

Showing the first eight; more decompositions exist.
