Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678690, here are decompositions:

19 + 8678671 = 8678690
103 + 8678587 = 8678690
109 + 8678581 = 8678690
331 + 8678359 = 8678690
337 + 8678353 = 8678690
367 + 8678323 = 8678690
379 + 8678311 = 8678690
487 + 8678203 = 8678690

Showing the first eight; more decompositions exist.
