Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945986, here are decompositions:

3 + 945983 = 945986
37 + 945949 = 945986
43 + 945943 = 945986
79 + 945907 = 945986
103 + 945883 = 945986
163 + 945823 = 945986
199 + 945787 = 945986
313 + 945673 = 945986

Showing the first eight; more decompositions exist.
