Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722576, here are decompositions:

59 + 8722517 = 8722576
167 + 8722409 = 8722576
293 + 8722283 = 8722576
353 + 8722223 = 8722576
383 + 8722193 = 8722576
389 + 8722187 = 8722576
479 + 8722097 = 8722576
557 + 8722019 = 8722576

Showing the first eight; more decompositions exist.
