Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701930, here are decompositions:

23 + 8701907 = 8701930
47 + 8701883 = 8701930
53 + 8701877 = 8701930
59 + 8701871 = 8701930
173 + 8701757 = 8701930
227 + 8701703 = 8701930
353 + 8701577 = 8701930
359 + 8701571 = 8701930

Showing the first eight; more decompositions exist.
