Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945664, here are decompositions:

17 + 945647 = 945664
191 + 945473 = 945664
233 + 945431 = 945664
431 + 945233 = 945664
521 + 945143 = 945664
677 + 944987 = 945664
701 + 944963 = 945664
887 + 944777 = 945664

Showing the first eight; more decompositions exist.
