Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631976, here are decompositions:

83 + 8631893 = 8631976
173 + 8631803 = 8631976
233 + 8631743 = 8631976
239 + 8631737 = 8631976
263 + 8631713 = 8631976
317 + 8631659 = 8631976
347 + 8631629 = 8631976
359 + 8631617 = 8631976

Showing the first eight; more decompositions exist.
