Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78264, here are decompositions:

5 + 78259 = 78264
23 + 78241 = 78264
31 + 78233 = 78264
61 + 78203 = 78264
71 + 78193 = 78264
73 + 78191 = 78264
97 + 78167 = 78264
101 + 78163 = 78264

Showing the first eight; more decompositions exist.
