Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151566, here are decompositions:

5 + 151561 = 151566
13 + 151553 = 151566
17 + 151549 = 151566
29 + 151537 = 151566
43 + 151523 = 151566
59 + 151507 = 151566
67 + 151499 = 151566
83 + 151483 = 151566

Showing the first eight; more decompositions exist.
