Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759828, here are decompositions:

31 + 8759797 = 8759828
67 + 8759761 = 8759828
79 + 8759749 = 8759828
97 + 8759731 = 8759828
139 + 8759689 = 8759828
151 + 8759677 = 8759828
271 + 8759557 = 8759828
307 + 8759521 = 8759828

Showing the first eight; more decompositions exist.
