Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152666, here are decompositions:

37 + 152629 = 152666
43 + 152623 = 152666
67 + 152599 = 152666
103 + 152563 = 152666
127 + 152539 = 152666
223 + 152443 = 152666
277 + 152389 = 152666
373 + 152293 = 152666

Showing the first eight; more decompositions exist.
