Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617870, here are decompositions:

47 + 8617823 = 8617870
71 + 8617799 = 8617870
83 + 8617787 = 8617870
101 + 8617769 = 8617870
167 + 8617703 = 8617870
347 + 8617523 = 8617870
431 + 8617439 = 8617870
479 + 8617391 = 8617870

Showing the first eight; more decompositions exist.
