Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701690, here are decompositions:

47 + 8701643 = 8701690
59 + 8701631 = 8701690
113 + 8701577 = 8701690
131 + 8701559 = 8701690
191 + 8701499 = 8701690
197 + 8701493 = 8701690
233 + 8701457 = 8701690
281 + 8701409 = 8701690

Showing the first eight; more decompositions exist.
