Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722786, here are decompositions:

29 + 8722757 = 8722786
47 + 8722739 = 8722786
113 + 8722673 = 8722786
173 + 8722613 = 8722786
179 + 8722607 = 8722786
269 + 8722517 = 8722786
419 + 8722367 = 8722786
503 + 8722283 = 8722786

Showing the first eight; more decompositions exist.
