Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73686, here are decompositions:

5 + 73681 = 73686
7 + 73679 = 73686
13 + 73673 = 73686
43 + 73643 = 73686
73 + 73613 = 73686
79 + 73607 = 73686
89 + 73597 = 73686
97 + 73589 = 73686

Showing the first eight; more decompositions exist.
