Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738284, here are decompositions:

3 + 8738281 = 8738284
11 + 8738273 = 8738284
53 + 8738231 = 8738284
83 + 8738201 = 8738284
197 + 8738087 = 8738284
251 + 8738033 = 8738284
521 + 8737763 = 8738284
587 + 8737697 = 8738284

Showing the first eight; more decompositions exist.
