Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645086, here are decompositions:

5 + 8645081 = 8645086
137 + 8644949 = 8645086
167 + 8644919 = 8645086
173 + 8644913 = 8645086
383 + 8644703 = 8645086
479 + 8644607 = 8645086
557 + 8644529 = 8645086
587 + 8644499 = 8645086

Showing the first eight; more decompositions exist.
