Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148728, here are decompositions:

5 + 148723 = 148728
7 + 148721 = 148728
17 + 148711 = 148728
37 + 148691 = 148728
59 + 148669 = 148728
61 + 148667 = 148728
89 + 148639 = 148728
101 + 148627 = 148728

Showing the first eight; more decompositions exist.
