Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78424, here are decompositions:

23 + 78401 = 78424
83 + 78341 = 78424
107 + 78317 = 78424
113 + 78311 = 78424
191 + 78233 = 78424
233 + 78191 = 78424
251 + 78173 = 78424
257 + 78167 = 78424

Showing the first eight; more decompositions exist.
