Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149802, here are decompositions:

11 + 149791 = 149802
31 + 149771 = 149802
43 + 149759 = 149802
53 + 149749 = 149802
71 + 149731 = 149802
73 + 149729 = 149802
89 + 149713 = 149802
113 + 149689 = 149802

Showing the first eight; more decompositions exist.
