Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148806, here are decompositions:

13 + 148793 = 148806
23 + 148783 = 148806
43 + 148763 = 148806
59 + 148747 = 148806
79 + 148727 = 148806
83 + 148723 = 148806
113 + 148693 = 148806
137 + 148669 = 148806

Showing the first eight; more decompositions exist.
