Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148820, here are decompositions:

3 + 148817 = 148820
37 + 148783 = 148820
73 + 148747 = 148820
97 + 148723 = 148820
109 + 148711 = 148820
127 + 148693 = 148820
151 + 148669 = 148820
157 + 148663 = 148820

Showing the first eight; more decompositions exist.
