Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675646, here are decompositions:

73 + 8675573 = 8675646
137 + 8675509 = 8675646
173 + 8675473 = 8675646
197 + 8675449 = 8675646
233 + 8675413 = 8675646
263 + 8675383 = 8675646
269 + 8675377 = 8675646
337 + 8675309 = 8675646

Showing the first eight; more decompositions exist.
