Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130746, here are decompositions:

17 + 130729 = 130746
47 + 130699 = 130746
53 + 130693 = 130746
59 + 130687 = 130746
89 + 130657 = 130746
97 + 130649 = 130746
103 + 130643 = 130746
107 + 130639 = 130746

Showing the first eight; more decompositions exist.
