Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151656, here are decompositions:

5 + 151651 = 151656
13 + 151643 = 151656
19 + 151637 = 151656
47 + 151609 = 151656
53 + 151603 = 151656
59 + 151597 = 151656
83 + 151573 = 151656
103 + 151553 = 151656

Showing the first eight; more decompositions exist.
