Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747678, here are decompositions:

61 + 8747617 = 8747678
139 + 8747539 = 8747678
151 + 8747527 = 8747678
271 + 8747407 = 8747678
349 + 8747329 = 8747678
421 + 8747257 = 8747678
487 + 8747191 = 8747678
607 + 8747071 = 8747678

Showing the first eight; more decompositions exist.
