Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628942, here are decompositions:

5 + 8628937 = 8628942
19 + 8628923 = 8628942
29 + 8628913 = 8628942
43 + 8628899 = 8628942
53 + 8628889 = 8628942
59 + 8628883 = 8628942
83 + 8628859 = 8628942
131 + 8628811 = 8628942

Showing the first eight; more decompositions exist.
