Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30540, here are decompositions:

11 + 30529 = 30540
23 + 30517 = 30540
31 + 30509 = 30540
43 + 30497 = 30540
47 + 30493 = 30540
71 + 30469 = 30540
73 + 30467 = 30540
109 + 30431 = 30540

Showing the first eight; more decompositions exist.
