Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678680, here are decompositions:

11 + 8678669 = 8678680
41 + 8678639 = 8678680
173 + 8678507 = 8678680
233 + 8678447 = 8678680
281 + 8678399 = 8678680
317 + 8678363 = 8678680
347 + 8678333 = 8678680
443 + 8678237 = 8678680

Showing the first eight; more decompositions exist.
