Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745866, here are decompositions:

37 + 8745829 = 8745866
67 + 8745799 = 8745866
163 + 8745703 = 8745866
229 + 8745637 = 8745866
313 + 8745553 = 8745866
373 + 8745493 = 8745866
499 + 8745367 = 8745866
523 + 8745343 = 8745866

Showing the first eight; more decompositions exist.
