Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945900, here are decompositions:

13 + 945887 = 945900
17 + 945883 = 945900
19 + 945881 = 945900
83 + 945817 = 945900
89 + 945811 = 945900
101 + 945799 = 945900
113 + 945787 = 945900
167 + 945733 = 945900

Showing the first eight; more decompositions exist.
