Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156746, here are decompositions:

13 + 156733 = 156746
19 + 156727 = 156746
43 + 156703 = 156746
67 + 156679 = 156746
127 + 156619 = 156746
157 + 156589 = 156746
439 + 156307 = 156746
487 + 156259 = 156746

Showing the first eight; more decompositions exist.
