Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701888, here are decompositions:

5 + 8701883 = 8701888
11 + 8701877 = 8701888
17 + 8701871 = 8701888
131 + 8701757 = 8701888
179 + 8701709 = 8701888
257 + 8701631 = 8701888
311 + 8701577 = 8701888
317 + 8701571 = 8701888

Showing the first eight; more decompositions exist.
