Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678446, here are decompositions:

47 + 8678399 = 8678446
53 + 8678393 = 8678446
83 + 8678363 = 8678446
107 + 8678339 = 8678446
113 + 8678333 = 8678446
233 + 8678213 = 8678446
317 + 8678129 = 8678446
353 + 8678093 = 8678446

Showing the first eight; more decompositions exist.
