Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671874, here are decompositions:

37 + 8671837 = 8671874
163 + 8671711 = 8671874
241 + 8671633 = 8671874
373 + 8671501 = 8671874
433 + 8671441 = 8671874
643 + 8671231 = 8671874
727 + 8671147 = 8671874
811 + 8671063 = 8671874

Showing the first eight; more decompositions exist.
