Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73620, here are decompositions:

7 + 73613 = 73620
11 + 73609 = 73620
13 + 73607 = 73620
23 + 73597 = 73620
31 + 73589 = 73620
37 + 73583 = 73620
59 + 73561 = 73620
67 + 73553 = 73620

Showing the first eight; more decompositions exist.
