Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722694, here are decompositions:

73 + 8722621 = 8722694
223 + 8722471 = 8722694
271 + 8722423 = 8722694
397 + 8722297 = 8722694
457 + 8722237 = 8722694
523 + 8722171 = 8722694
571 + 8722123 = 8722694
577 + 8722117 = 8722694

Showing the first eight; more decompositions exist.
