Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73520, here are decompositions:

3 + 73517 = 73520
37 + 73483 = 73520
43 + 73477 = 73520
61 + 73459 = 73520
67 + 73453 = 73520
103 + 73417 = 73520
151 + 73369 = 73520
157 + 73363 = 73520

Showing the first eight; more decompositions exist.
