Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685404, here are decompositions:

31 + 8685373 = 8685404
37 + 8685367 = 8685404
151 + 8685253 = 8685404
193 + 8685211 = 8685404
331 + 8685073 = 8685404
373 + 8685031 = 8685404
421 + 8684983 = 8685404
457 + 8684947 = 8685404

Showing the first eight; more decompositions exist.
