Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761678, here are decompositions:

47 + 8761631 = 8761678
59 + 8761619 = 8761678
131 + 8761547 = 8761678
239 + 8761439 = 8761678
389 + 8761289 = 8761678
509 + 8761169 = 8761678
521 + 8761157 = 8761678
599 + 8761079 = 8761678

Showing the first eight; more decompositions exist.
