Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151626, here are decompositions:

17 + 151609 = 151626
19 + 151607 = 151626
23 + 151603 = 151626
29 + 151597 = 151626
47 + 151579 = 151626
53 + 151573 = 151626
73 + 151553 = 151626
89 + 151537 = 151626

Showing the first eight; more decompositions exist.
