Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148992, here are decompositions:

31 + 148961 = 148992
43 + 148949 = 148992
59 + 148933 = 148992
61 + 148931 = 148992
71 + 148921 = 148992
79 + 148913 = 148992
101 + 148891 = 148992
131 + 148861 = 148992

Showing the first eight; more decompositions exist.
