Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701918, here are decompositions:

11 + 8701907 = 8701918
41 + 8701877 = 8701918
47 + 8701871 = 8701918
107 + 8701811 = 8701918
347 + 8701571 = 8701918
359 + 8701559 = 8701918
389 + 8701529 = 8701918
419 + 8701499 = 8701918

Showing the first eight; more decompositions exist.
