Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149550, here are decompositions:

7 + 149543 = 149550
17 + 149533 = 149550
19 + 149531 = 149550
29 + 149521 = 149550
31 + 149519 = 149550
47 + 149503 = 149550
53 + 149497 = 149550
59 + 149491 = 149550

Showing the first eight; more decompositions exist.
