Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78268, here are decompositions:

89 + 78179 = 78268
101 + 78167 = 78268
131 + 78137 = 78268
167 + 78101 = 78268
227 + 78041 = 78268
251 + 78017 = 78268
269 + 77999 = 78268
317 + 77951 = 78268

Showing the first eight; more decompositions exist.
