Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719966, here are decompositions:

5 + 8719961 = 8719966
23 + 8719943 = 8719966
149 + 8719817 = 8719966
263 + 8719703 = 8719966
389 + 8719577 = 8719966
587 + 8719379 = 8719966
599 + 8719367 = 8719966
617 + 8719349 = 8719966

Showing the first eight; more decompositions exist.
