Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152718, here are decompositions:

37 + 152681 = 152718
47 + 152671 = 152718
61 + 152657 = 152718
79 + 152639 = 152718
89 + 152629 = 152718
101 + 152617 = 152718
151 + 152567 = 152718
179 + 152539 = 152718

Showing the first eight; more decompositions exist.
