Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728346, here are decompositions:

37 + 8728309 = 8728346
43 + 8728303 = 8728346
73 + 8728273 = 8728346
139 + 8728207 = 8728346
199 + 8728147 = 8728346
409 + 8727937 = 8728346
433 + 8727913 = 8728346
439 + 8727907 = 8728346

Showing the first eight; more decompositions exist.
