Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7724, here are decompositions:

7 + 7717 = 7724
37 + 7687 = 7724
43 + 7681 = 7724
103 + 7621 = 7724
151 + 7573 = 7724
163 + 7561 = 7724
307 + 7417 = 7724
313 + 7411 = 7724

Showing the first eight; more decompositions exist.
