Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993540, here are decompositions:

13 + 993527 = 993540
47 + 993493 = 993540
59 + 993481 = 993540
61 + 993479 = 993540
73 + 993467 = 993540
89 + 993451 = 993540
103 + 993437 = 993540
109 + 993431 = 993540

Showing the first eight; more decompositions exist.
