Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637042, here are decompositions:

53 + 8636989 = 8637042
83 + 8636959 = 8637042
131 + 8636911 = 8637042
149 + 8636893 = 8637042
173 + 8636869 = 8637042
223 + 8636819 = 8637042
241 + 8636801 = 8637042
251 + 8636791 = 8637042

Showing the first eight; more decompositions exist.
