Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945490, here are decompositions:

11 + 945479 = 945490
17 + 945473 = 945490
59 + 945431 = 945490
101 + 945389 = 945490
113 + 945377 = 945490
131 + 945359 = 945490
149 + 945341 = 945490
197 + 945293 = 945490

Showing the first eight; more decompositions exist.
