Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639954, here are decompositions:

3 + 8639951 = 8639954
31 + 8639923 = 8639954
151 + 8639803 = 8639954
157 + 8639797 = 8639954
181 + 8639773 = 8639954
241 + 8639713 = 8639954
307 + 8639647 = 8639954
541 + 8639413 = 8639954

Showing the first eight; more decompositions exist.
