Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719902, here are decompositions:

29 + 8719873 = 8719902
71 + 8719831 = 8719902
83 + 8719819 = 8719902
89 + 8719813 = 8719902
101 + 8719801 = 8719902
131 + 8719771 = 8719902
199 + 8719703 = 8719902
239 + 8719663 = 8719902

Showing the first eight; more decompositions exist.
