Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945648, here are decompositions:

17 + 945631 = 945648
19 + 945629 = 945648
47 + 945601 = 945648
59 + 945589 = 945648
61 + 945587 = 945648
71 + 945577 = 945648
101 + 945547 = 945648
127 + 945521 = 945648

Showing the first eight; more decompositions exist.
