Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148686, here are decompositions:

17 + 148669 = 148686
19 + 148667 = 148686
23 + 148663 = 148686
47 + 148639 = 148686
53 + 148633 = 148686
59 + 148627 = 148686
107 + 148579 = 148686
113 + 148573 = 148686

Showing the first eight; more decompositions exist.
