Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719942, here are decompositions:

3 + 8719939 = 8719942
239 + 8719703 = 8719942
281 + 8719661 = 8719942
401 + 8719541 = 8719942
521 + 8719421 = 8719942
563 + 8719379 = 8719942
593 + 8719349 = 8719942
641 + 8719301 = 8719942

Showing the first eight; more decompositions exist.
