Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728244, here are decompositions:

3 + 8728241 = 8728244
37 + 8728207 = 8728244
97 + 8728147 = 8728244
307 + 8727937 = 8728244
313 + 8727931 = 8728244
331 + 8727913 = 8728244
337 + 8727907 = 8728244
373 + 8727871 = 8728244

Showing the first eight; more decompositions exist.
