Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949540, here are decompositions:

17 + 949523 = 949540
23 + 949517 = 949540
89 + 949451 = 949540
101 + 949439 = 949540
113 + 949427 = 949540
131 + 949409 = 949540
149 + 949391 = 949540
233 + 949307 = 949540

Showing the first eight; more decompositions exist.
