Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523530, here are decompositions:

11 + 523519 = 523530
19 + 523511 = 523530
37 + 523493 = 523530
41 + 523489 = 523530
43 + 523487 = 523530
67 + 523463 = 523530
71 + 523459 = 523530
97 + 523433 = 523530

Showing the first eight; more decompositions exist.
