Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156744, here are decompositions:

11 + 156733 = 156744
17 + 156727 = 156744
37 + 156707 = 156744
41 + 156703 = 156744
53 + 156691 = 156744
61 + 156683 = 156744
67 + 156677 = 156744
73 + 156671 = 156744

Showing the first eight; more decompositions exist.
