Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718394, here are decompositions:

17 + 8718377 = 8718394
173 + 8718221 = 8718394
197 + 8718197 = 8718394
281 + 8718113 = 8718394
383 + 8718011 = 8718394
401 + 8717993 = 8718394
431 + 8717963 = 8718394
467 + 8717927 = 8718394

Showing the first eight; more decompositions exist.
