Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151746, here are decompositions:

13 + 151733 = 151746
17 + 151729 = 151746
29 + 151717 = 151746
43 + 151703 = 151746
53 + 151693 = 151746
59 + 151687 = 151746
73 + 151673 = 151746
79 + 151667 = 151746

Showing the first eight; more decompositions exist.
