Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722426, here are decompositions:

3 + 8722423 = 8722426
17 + 8722409 = 8722426
59 + 8722367 = 8722426
233 + 8722193 = 8722426
239 + 8722187 = 8722426
257 + 8722169 = 8722426
347 + 8722079 = 8722426
509 + 8721917 = 8722426

Showing the first eight; more decompositions exist.
