Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103712, here are decompositions:

13 + 103699 = 103712
31 + 103681 = 103712
43 + 103669 = 103712
61 + 103651 = 103712
139 + 103573 = 103712
151 + 103561 = 103712
163 + 103549 = 103712
229 + 103483 = 103712

Showing the first eight; more decompositions exist.
