Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148554, here are decompositions:

5 + 148549 = 148554
17 + 148537 = 148554
23 + 148531 = 148554
37 + 148517 = 148554
41 + 148513 = 148554
53 + 148501 = 148554
71 + 148483 = 148554
83 + 148471 = 148554

Showing the first eight; more decompositions exist.
