Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631964, here are decompositions:

53 + 8631911 = 8631964
71 + 8631893 = 8631964
83 + 8631881 = 8631964
113 + 8631851 = 8631964
227 + 8631737 = 8631964
251 + 8631713 = 8631964
347 + 8631617 = 8631964
353 + 8631611 = 8631964

Showing the first eight; more decompositions exist.
