Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722814, here are decompositions:

103 + 8722711 = 8722814
193 + 8722621 = 8722814
211 + 8722603 = 8722814
337 + 8722477 = 8722814
367 + 8722447 = 8722814
421 + 8722393 = 8722814
523 + 8722291 = 8722814
577 + 8722237 = 8722814

Showing the first eight; more decompositions exist.
