Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625874, here are decompositions:

41 + 8625833 = 8625874
53 + 8625821 = 8625874
167 + 8625707 = 8625874
233 + 8625641 = 8625874
347 + 8625527 = 8625874
353 + 8625521 = 8625874
443 + 8625431 = 8625874
557 + 8625317 = 8625874

Showing the first eight; more decompositions exist.
