Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745446, here are decompositions:

79 + 8745367 = 8745446
103 + 8745343 = 8745446
139 + 8745307 = 8745446
223 + 8745223 = 8745446
277 + 8745169 = 8745446
313 + 8745133 = 8745446
349 + 8745097 = 8745446
379 + 8745067 = 8745446

Showing the first eight; more decompositions exist.
