Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688958, here are decompositions:

149 + 8688809 = 8688958
167 + 8688791 = 8688958
251 + 8688707 = 8688958
347 + 8688611 = 8688958
389 + 8688569 = 8688958
401 + 8688557 = 8688958
431 + 8688527 = 8688958
461 + 8688497 = 8688958

Showing the first eight; more decompositions exist.
