Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148566, here are decompositions:

17 + 148549 = 148566
29 + 148537 = 148566
53 + 148513 = 148566
83 + 148483 = 148566
97 + 148469 = 148566
109 + 148457 = 148566
127 + 148439 = 148566
137 + 148429 = 148566

Showing the first eight; more decompositions exist.
