Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146808, here are decompositions:

7 + 146801 = 146808
31 + 146777 = 146808
41 + 146767 = 146808
59 + 146749 = 146808
89 + 146719 = 146808
107 + 146701 = 146808
127 + 146681 = 146808
131 + 146677 = 146808

Showing the first eight; more decompositions exist.
