Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148290, here are decompositions:

11 + 148279 = 148290
41 + 148249 = 148290
47 + 148243 = 148290
61 + 148229 = 148290
83 + 148207 = 148290
89 + 148201 = 148290
97 + 148193 = 148290
137 + 148153 = 148290

Showing the first eight; more decompositions exist.
