Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148218, here are decompositions:

11 + 148207 = 148218
17 + 148201 = 148218
19 + 148199 = 148218
47 + 148171 = 148218
61 + 148157 = 148218
67 + 148151 = 148218
71 + 148147 = 148218
79 + 148139 = 148218

Showing the first eight; more decompositions exist.
