Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479140, here are decompositions:

3 + 479137 = 479140
59 + 479081 = 479140
113 + 479027 = 479140
149 + 478991 = 479140
173 + 478967 = 479140
197 + 478943 = 479140
227 + 478913 = 479140
239 + 478901 = 479140

Showing the first eight; more decompositions exist.
