Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945800, here are decompositions:

13 + 945787 = 945800
61 + 945739 = 945800
67 + 945733 = 945800
127 + 945673 = 945800
199 + 945601 = 945800
211 + 945589 = 945800
223 + 945577 = 945800
337 + 945463 = 945800

Showing the first eight; more decompositions exist.
