Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728074, here are decompositions:

37 + 8728037 = 8728074
137 + 8727937 = 8728074
167 + 8727907 = 8728074
283 + 8727791 = 8728074
307 + 8727767 = 8728074
317 + 8727757 = 8728074
347 + 8727727 = 8728074
373 + 8727701 = 8728074

Showing the first eight; more decompositions exist.
