Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634942, here are decompositions:

53 + 8634889 = 8634942
59 + 8634883 = 8634942
61 + 8634881 = 8634942
79 + 8634863 = 8634942
83 + 8634859 = 8634942
101 + 8634841 = 8634942
103 + 8634839 = 8634942
131 + 8634811 = 8634942

Showing the first eight; more decompositions exist.
