Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631042, here are decompositions:

5 + 8631037 = 8631042
19 + 8631023 = 8631042
31 + 8631011 = 8631042
41 + 8631001 = 8631042
59 + 8630983 = 8631042
71 + 8630971 = 8631042
113 + 8630929 = 8631042
139 + 8630903 = 8631042

Showing the first eight; more decompositions exist.
