Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719750, here are decompositions:

3 + 8719747 = 8719750
47 + 8719703 = 8719750
89 + 8719661 = 8719750
173 + 8719577 = 8719750
359 + 8719391 = 8719750
383 + 8719367 = 8719750
401 + 8719349 = 8719750
443 + 8719307 = 8719750

Showing the first eight; more decompositions exist.
