Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718574, here are decompositions:

3 + 8718571 = 8718574
71 + 8718503 = 8718574
83 + 8718491 = 8718574
113 + 8718461 = 8718574
167 + 8718407 = 8718574
173 + 8718401 = 8718574
197 + 8718377 = 8718574
353 + 8718221 = 8718574

Showing the first eight; more decompositions exist.
