Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78422, here are decompositions:

139 + 78283 = 78422
163 + 78259 = 78422
181 + 78241 = 78422
193 + 78229 = 78422
229 + 78193 = 78422
283 + 78139 = 78422
373 + 78049 = 78422
439 + 77983 = 78422

Showing the first eight; more decompositions exist.
