Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148668, here are decompositions:

5 + 148663 = 148668
29 + 148639 = 148668
41 + 148627 = 148668
59 + 148609 = 148668
89 + 148579 = 148668
131 + 148537 = 148668
137 + 148531 = 148668
151 + 148517 = 148668

Showing the first eight; more decompositions exist.
