Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631930, here are decompositions:

19 + 8631911 = 8631930
23 + 8631907 = 8631930
31 + 8631899 = 8631930
37 + 8631893 = 8631930
79 + 8631851 = 8631930
107 + 8631823 = 8631930
127 + 8631803 = 8631930
149 + 8631781 = 8631930

Showing the first eight; more decompositions exist.
