Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148788, here are decompositions:

5 + 148783 = 148788
7 + 148781 = 148788
41 + 148747 = 148788
61 + 148727 = 148788
67 + 148721 = 148788
97 + 148691 = 148788
149 + 148639 = 148788
179 + 148609 = 148788

Showing the first eight; more decompositions exist.
