Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722984, here are decompositions:

3 + 8722981 = 8722984
71 + 8722913 = 8722984
107 + 8722877 = 8722984
227 + 8722757 = 8722984
311 + 8722673 = 8722984
353 + 8722631 = 8722984
443 + 8722541 = 8722984
467 + 8722517 = 8722984

Showing the first eight; more decompositions exist.
