Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719994, here are decompositions:

7 + 8719987 = 8719994
43 + 8719951 = 8719994
163 + 8719831 = 8719994
181 + 8719813 = 8719994
193 + 8719801 = 8719994
223 + 8719771 = 8719994
313 + 8719681 = 8719994
331 + 8719663 = 8719994

Showing the first eight; more decompositions exist.
