Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720886, here are decompositions:

47 + 8720839 = 8720886
67 + 8720819 = 8720886
79 + 8720807 = 8720886
89 + 8720797 = 8720886
103 + 8720783 = 8720886
113 + 8720773 = 8720886
157 + 8720729 = 8720886
173 + 8720713 = 8720886

Showing the first eight; more decompositions exist.
