Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631070, here are decompositions:

29 + 8631041 = 8631070
47 + 8631023 = 8631070
53 + 8631017 = 8631070
59 + 8631011 = 8631070
167 + 8630903 = 8631070
233 + 8630837 = 8631070
257 + 8630813 = 8631070
281 + 8630789 = 8631070

Showing the first eight; more decompositions exist.
