Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151770, here are decompositions:

37 + 151733 = 151770
41 + 151729 = 151770
53 + 151717 = 151770
67 + 151703 = 151770
83 + 151687 = 151770
89 + 151681 = 151770
97 + 151673 = 151770
103 + 151667 = 151770

Showing the first eight; more decompositions exist.
