Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103772, here are decompositions:

3 + 103769 = 103772
73 + 103699 = 103772
103 + 103669 = 103772
181 + 103591 = 103772
199 + 103573 = 103772
211 + 103561 = 103772
223 + 103549 = 103772
349 + 103423 = 103772

Showing the first eight; more decompositions exist.
