Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30520, here are decompositions:

3 + 30517 = 30520
11 + 30509 = 30520
23 + 30497 = 30520
29 + 30491 = 30520
53 + 30467 = 30520
71 + 30449 = 30520
89 + 30431 = 30520
131 + 30389 = 30520

Showing the first eight; more decompositions exist.
