Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700838, here are decompositions:

5 + 8700833 = 8700838
11 + 8700827 = 8700838
71 + 8700767 = 8700838
239 + 8700599 = 8700838
257 + 8700581 = 8700838
317 + 8700521 = 8700838
389 + 8700449 = 8700838
431 + 8700407 = 8700838

Showing the first eight; more decompositions exist.
