Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73530, here are decompositions:

7 + 73523 = 73530
13 + 73517 = 73530
47 + 73483 = 73530
53 + 73477 = 73530
59 + 73471 = 73530
71 + 73459 = 73530
97 + 73433 = 73530
109 + 73421 = 73530

Showing the first eight; more decompositions exist.
