Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149652, here are decompositions:

23 + 149629 = 149652
29 + 149623 = 149652
73 + 149579 = 149652
89 + 149563 = 149652
101 + 149551 = 149652
109 + 149543 = 149652
131 + 149521 = 149652
149 + 149503 = 149652

Showing the first eight; more decompositions exist.
