Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152660, here are decompositions:

3 + 152657 = 152660
19 + 152641 = 152660
31 + 152629 = 152660
37 + 152623 = 152660
43 + 152617 = 152660
61 + 152599 = 152660
97 + 152563 = 152660
127 + 152533 = 152660

Showing the first eight; more decompositions exist.
