Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78436, here are decompositions:

89 + 78347 = 78436
233 + 78203 = 78436
257 + 78179 = 78436
263 + 78173 = 78436
269 + 78167 = 78436
419 + 78017 = 78436
467 + 77969 = 78436
503 + 77933 = 78436

Showing the first eight; more decompositions exist.
