Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745566, here are decompositions:

13 + 8745553 = 8745566
19 + 8745547 = 8745566
43 + 8745523 = 8745566
73 + 8745493 = 8745566
199 + 8745367 = 8745566
223 + 8745343 = 8745566
367 + 8745199 = 8745566
397 + 8745169 = 8745566

Showing the first eight; more decompositions exist.
