Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619970, here are decompositions:

101 + 8619869 = 8619970
113 + 8619857 = 8619970
173 + 8619797 = 8619970
179 + 8619791 = 8619970
197 + 8619773 = 8619970
251 + 8619719 = 8619970
257 + 8619713 = 8619970
347 + 8619623 = 8619970

Showing the first eight; more decompositions exist.
