Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151608, here are decompositions:

5 + 151603 = 151608
11 + 151597 = 151608
29 + 151579 = 151608
47 + 151561 = 151608
59 + 151549 = 151608
71 + 151537 = 151608
101 + 151507 = 151608
109 + 151499 = 151608

Showing the first eight; more decompositions exist.
