Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709678, here are decompositions:

31 + 8709647 = 8709678
67 + 8709611 = 8709678
151 + 8709527 = 8709678
317 + 8709361 = 8709678
379 + 8709299 = 8709678
389 + 8709289 = 8709678
421 + 8709257 = 8709678
449 + 8709229 = 8709678

Showing the first eight; more decompositions exist.
