Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719944, here are decompositions:

5 + 8719939 = 8719944
41 + 8719903 = 8719944
71 + 8719873 = 8719944
97 + 8719847 = 8719944
113 + 8719831 = 8719944
127 + 8719817 = 8719944
131 + 8719813 = 8719944
173 + 8719771 = 8719944

Showing the first eight; more decompositions exist.
