Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123370, here are decompositions:

29 + 123341 = 123370
47 + 123323 = 123370
59 + 123311 = 123370
101 + 123269 = 123370
131 + 123239 = 123370
167 + 123203 = 123370
179 + 123191 = 123370
227 + 123143 = 123370

Showing the first eight; more decompositions exist.
