Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701620, here are decompositions:

43 + 8701577 = 8701620
61 + 8701559 = 8701620
89 + 8701531 = 8701620
101 + 8701519 = 8701620
113 + 8701507 = 8701620
127 + 8701493 = 8701620
131 + 8701489 = 8701620
163 + 8701457 = 8701620

Showing the first eight; more decompositions exist.
