Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945618, here are decompositions:

17 + 945601 = 945618
29 + 945589 = 945618
31 + 945587 = 945618
41 + 945577 = 945618
71 + 945547 = 945618
97 + 945521 = 945618
137 + 945481 = 945618
139 + 945479 = 945618

Showing the first eight; more decompositions exist.
