Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947828, here are decompositions:

109 + 947719 = 947828
181 + 947647 = 947828
379 + 947449 = 947828
397 + 947431 = 947828
421 + 947407 = 947828
439 + 947389 = 947828
487 + 947341 = 947828
631 + 947197 = 947828

Showing the first eight; more decompositions exist.
