Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645158, here are decompositions:

17 + 8645141 = 8645158
149 + 8645009 = 8645158
167 + 8644991 = 8645158
239 + 8644919 = 8645158
359 + 8644799 = 8645158
479 + 8644679 = 8645158
647 + 8644511 = 8645158
659 + 8644499 = 8645158

Showing the first eight; more decompositions exist.
