Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152688, here are decompositions:

7 + 152681 = 152688
17 + 152671 = 152688
31 + 152657 = 152688
47 + 152641 = 152688
59 + 152629 = 152688
71 + 152617 = 152688
89 + 152599 = 152688
149 + 152539 = 152688

Showing the first eight; more decompositions exist.
