Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149574, here are decompositions:

11 + 149563 = 149574
13 + 149561 = 149574
23 + 149551 = 149574
31 + 149543 = 149574
41 + 149533 = 149574
43 + 149531 = 149574
53 + 149521 = 149574
71 + 149503 = 149574

Showing the first eight; more decompositions exist.
