Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744146, here are decompositions:

3 + 8744143 = 8744146
17 + 8744129 = 8744146
83 + 8744063 = 8744146
113 + 8744033 = 8744146
149 + 8743997 = 8744146
227 + 8743919 = 8744146
233 + 8743913 = 8744146
263 + 8743883 = 8744146

Showing the first eight; more decompositions exist.
