Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945850, here are decompositions:

41 + 945809 = 945850
83 + 945767 = 945850
149 + 945701 = 945850
173 + 945677 = 945850
179 + 945671 = 945850
263 + 945587 = 945850
419 + 945431 = 945850
461 + 945389 = 945850

Showing the first eight; more decompositions exist.
