Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646778, here are decompositions:

59 + 8646719 = 8646778
71 + 8646707 = 8646778
197 + 8646581 = 8646778
281 + 8646497 = 8646778
389 + 8646389 = 8646778
401 + 8646377 = 8646778
449 + 8646329 = 8646778
461 + 8646317 = 8646778

Showing the first eight; more decompositions exist.
