Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722790, here are decompositions:

79 + 8722711 = 8722790
313 + 8722477 = 8722790
331 + 8722459 = 8722790
367 + 8722423 = 8722790
397 + 8722393 = 8722790
457 + 8722333 = 8722790
487 + 8722303 = 8722790
499 + 8722291 = 8722790

Showing the first eight; more decompositions exist.
