Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148518, here are decompositions:

5 + 148513 = 148518
17 + 148501 = 148518
47 + 148471 = 148518
61 + 148457 = 148518
79 + 148439 = 148518
89 + 148429 = 148518
107 + 148411 = 148518
131 + 148387 = 148518

Showing the first eight; more decompositions exist.
