Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728292, here are decompositions:

3 + 8728289 = 8728292
19 + 8728273 = 8728292
31 + 8728261 = 8728292
163 + 8728129 = 8728292
379 + 8727913 = 8728292
421 + 8727871 = 8728292
619 + 8727673 = 8728292
673 + 8727619 = 8728292

Showing the first eight; more decompositions exist.
