Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744200, here are decompositions:

11 + 8744189 = 8744200
71 + 8744129 = 8744200
137 + 8744063 = 8744200
167 + 8744033 = 8744200
197 + 8744003 = 8744200
263 + 8743937 = 8744200
281 + 8743919 = 8744200
317 + 8743883 = 8744200

Showing the first eight; more decompositions exist.
