Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701078, here are decompositions:

11 + 8701067 = 8701078
131 + 8700947 = 8701078
137 + 8700941 = 8701078
167 + 8700911 = 8701078
251 + 8700827 = 8701078
311 + 8700767 = 8701078
479 + 8700599 = 8701078
557 + 8700521 = 8701078

Showing the first eight; more decompositions exist.
