Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690584, here are decompositions:

17 + 8690567 = 8690584
53 + 8690531 = 8690584
107 + 8690477 = 8690584
131 + 8690453 = 8690584
173 + 8690411 = 8690584
197 + 8690387 = 8690584
233 + 8690351 = 8690584
251 + 8690333 = 8690584

Showing the first eight; more decompositions exist.
