Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148644, here are decompositions:

5 + 148639 = 148644
11 + 148633 = 148644
17 + 148627 = 148644
71 + 148573 = 148644
107 + 148537 = 148644
113 + 148531 = 148644
127 + 148517 = 148644
131 + 148513 = 148644

Showing the first eight; more decompositions exist.
