Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728150, here are decompositions:

3 + 8728147 = 8728150
71 + 8728079 = 8728150
113 + 8728037 = 8728150
251 + 8727899 = 8728150
293 + 8727857 = 8728150
359 + 8727791 = 8728150
383 + 8727767 = 8728150
419 + 8727731 = 8728150

Showing the first eight; more decompositions exist.
