Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645486, here are decompositions:

37 + 8645449 = 8645486
43 + 8645443 = 8645486
79 + 8645407 = 8645486
127 + 8645359 = 8645486
193 + 8645293 = 8645486
229 + 8645257 = 8645486
307 + 8645179 = 8645486
373 + 8645113 = 8645486

Showing the first eight; more decompositions exist.
