Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148620, here are decompositions:

11 + 148609 = 148620
41 + 148579 = 148620
47 + 148573 = 148620
71 + 148549 = 148620
83 + 148537 = 148620
89 + 148531 = 148620
103 + 148517 = 148620
107 + 148513 = 148620

Showing the first eight; more decompositions exist.
