Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662778, here are decompositions:

31 + 8662747 = 8662778
181 + 8662597 = 8662778
199 + 8662579 = 8662778
307 + 8662471 = 8662778
331 + 8662447 = 8662778
337 + 8662441 = 8662778
367 + 8662411 = 8662778
499 + 8662279 = 8662778

Showing the first eight; more decompositions exist.
