Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688520, here are decompositions:

23 + 8688497 = 8688520
83 + 8688437 = 8688520
167 + 8688353 = 8688520
233 + 8688287 = 8688520
311 + 8688209 = 8688520
317 + 8688203 = 8688520
353 + 8688167 = 8688520
359 + 8688161 = 8688520

Showing the first eight; more decompositions exist.
