Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634042, here are decompositions:

59 + 8633983 = 8634042
61 + 8633981 = 8634042
71 + 8633971 = 8634042
83 + 8633959 = 8634042
101 + 8633941 = 8634042
103 + 8633939 = 8634042
149 + 8633893 = 8634042
173 + 8633869 = 8634042

Showing the first eight; more decompositions exist.
