Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130724, here are decompositions:

31 + 130693 = 130724
37 + 130687 = 130724
43 + 130681 = 130724
67 + 130657 = 130724
73 + 130651 = 130724
103 + 130621 = 130724
193 + 130531 = 130724
211 + 130513 = 130724

Showing the first eight; more decompositions exist.
