Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148548, here are decompositions:

11 + 148537 = 148548
17 + 148531 = 148548
31 + 148517 = 148548
47 + 148501 = 148548
79 + 148469 = 148548
109 + 148439 = 148548
137 + 148411 = 148548
149 + 148399 = 148548

Showing the first eight; more decompositions exist.
