Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940530, here are decompositions:

7 + 940523 = 940530
29 + 940501 = 940530
47 + 940483 = 940530
53 + 940477 = 940530
61 + 940469 = 940530
109 + 940421 = 940530
127 + 940403 = 940530
131 + 940399 = 940530

Showing the first eight; more decompositions exist.
