Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156786, here are decompositions:

5 + 156781 = 156786
37 + 156749 = 156786
53 + 156733 = 156786
59 + 156727 = 156786
67 + 156719 = 156786
79 + 156707 = 156786
83 + 156703 = 156786
103 + 156683 = 156786

Showing the first eight; more decompositions exist.
