Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748646, here are decompositions:

3 + 8748643 = 8748646
47 + 8748599 = 8748646
59 + 8748587 = 8748646
83 + 8748563 = 8748646
173 + 8748473 = 8748646
227 + 8748419 = 8748646
233 + 8748413 = 8748646
317 + 8748329 = 8748646

Showing the first eight; more decompositions exist.
