Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630742, here are decompositions:

5 + 8630737 = 8630742
59 + 8630683 = 8630742
73 + 8630669 = 8630742
79 + 8630663 = 8630742
89 + 8630653 = 8630742
101 + 8630641 = 8630742
103 + 8630639 = 8630742
149 + 8630593 = 8630742

Showing the first eight; more decompositions exist.
