Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644258, here are decompositions:

5 + 8644253 = 8644258
71 + 8644187 = 8644258
101 + 8644157 = 8644258
167 + 8644091 = 8644258
197 + 8644061 = 8644258
239 + 8644019 = 8644258
317 + 8643941 = 8644258
419 + 8643839 = 8644258

Showing the first eight; more decompositions exist.
