Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37530, here are decompositions:

13 + 37517 = 37530
19 + 37511 = 37530
23 + 37507 = 37530
29 + 37501 = 37530
37 + 37493 = 37530
41 + 37489 = 37530
47 + 37483 = 37530
67 + 37463 = 37530

Showing the first eight; more decompositions exist.
