Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668874, here are decompositions:

37 + 8668837 = 8668874
43 + 8668831 = 8668874
61 + 8668813 = 8668874
73 + 8668801 = 8668874
163 + 8668711 = 8668874
373 + 8668501 = 8668874
601 + 8668273 = 8668874
607 + 8668267 = 8668874

Showing the first eight; more decompositions exist.
