Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945660, here are decompositions:

13 + 945647 = 945660
29 + 945631 = 945660
31 + 945629 = 945660
59 + 945601 = 945660
71 + 945589 = 945660
73 + 945587 = 945660
83 + 945577 = 945660
113 + 945547 = 945660

Showing the first eight; more decompositions exist.
