Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149556, here are decompositions:

5 + 149551 = 149556
13 + 149543 = 149556
23 + 149533 = 149556
37 + 149519 = 149556
53 + 149503 = 149556
59 + 149497 = 149556
67 + 149489 = 149556
97 + 149459 = 149556

Showing the first eight; more decompositions exist.
