Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73680, here are decompositions:

7 + 73673 = 73680
29 + 73651 = 73680
37 + 73643 = 73680
43 + 73637 = 73680
67 + 73613 = 73680
71 + 73609 = 73680
73 + 73607 = 73680
83 + 73597 = 73680

Showing the first eight; more decompositions exist.
