Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743678, here are decompositions:

5 + 8743673 = 8743678
89 + 8743589 = 8743678
107 + 8743571 = 8743678
131 + 8743547 = 8743678
179 + 8743499 = 8743678
257 + 8743421 = 8743678
269 + 8743409 = 8743678
311 + 8743367 = 8743678

Showing the first eight; more decompositions exist.
