Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701578, here are decompositions:

7 + 8701571 = 8701578
19 + 8701559 = 8701578
47 + 8701531 = 8701578
59 + 8701519 = 8701578
71 + 8701507 = 8701578
79 + 8701499 = 8701578
89 + 8701489 = 8701578
101 + 8701477 = 8701578

Showing the first eight; more decompositions exist.
