Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945740, here are decompositions:

7 + 945733 = 945740
67 + 945673 = 945740
109 + 945631 = 945740
139 + 945601 = 945740
151 + 945589 = 945740
163 + 945577 = 945740
193 + 945547 = 945740
277 + 945463 = 945740

Showing the first eight; more decompositions exist.
