Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719984, here are decompositions:

23 + 8719961 = 8719984
41 + 8719943 = 8719984
137 + 8719847 = 8719984
167 + 8719817 = 8719984
281 + 8719703 = 8719984
443 + 8719541 = 8719984
563 + 8719421 = 8719984
593 + 8719391 = 8719984

Showing the first eight; more decompositions exist.
