Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148578, here are decompositions:

5 + 148573 = 148578
29 + 148549 = 148578
41 + 148537 = 148578
47 + 148531 = 148578
61 + 148517 = 148578
107 + 148471 = 148578
109 + 148469 = 148578
139 + 148439 = 148578

Showing the first eight; more decompositions exist.
