Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722726, here are decompositions:

53 + 8722673 = 8722726
83 + 8722643 = 8722726
113 + 8722613 = 8722726
227 + 8722499 = 8722726
317 + 8722409 = 8722726
359 + 8722367 = 8722726
443 + 8722283 = 8722726
503 + 8722223 = 8722726

Showing the first eight; more decompositions exist.
