Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719992, here are decompositions:

5 + 8719987 = 8719992
31 + 8719961 = 8719992
41 + 8719951 = 8719992
53 + 8719939 = 8719992
89 + 8719903 = 8719992
173 + 8719819 = 8719992
179 + 8719813 = 8719992
191 + 8719801 = 8719992

Showing the first eight; more decompositions exist.
