Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701648, here are decompositions:

5 + 8701643 = 8701648
17 + 8701631 = 8701648
71 + 8701577 = 8701648
89 + 8701559 = 8701648
149 + 8701499 = 8701648
191 + 8701457 = 8701648
239 + 8701409 = 8701648
257 + 8701391 = 8701648

Showing the first eight; more decompositions exist.
