Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622756, here are decompositions:

73 + 8622683 = 8622756
179 + 8622577 = 8622756
193 + 8622563 = 8622756
227 + 8622529 = 8622756
257 + 8622499 = 8622756
269 + 8622487 = 8622756
283 + 8622473 = 8622756
293 + 8622463 = 8622756

Showing the first eight; more decompositions exist.
