Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 132780, here are decompositions:

17 + 132763 = 132780
19 + 132761 = 132780
23 + 132757 = 132780
29 + 132751 = 132780
31 + 132749 = 132780
41 + 132739 = 132780
59 + 132721 = 132780
71 + 132709 = 132780

Showing the first eight; more decompositions exist.
