Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103690, here are decompositions:

3 + 103687 = 103690
47 + 103643 = 103690
71 + 103619 = 103690
107 + 103583 = 103690
113 + 103577 = 103690
137 + 103553 = 103690
179 + 103511 = 103690
233 + 103457 = 103690

Showing the first eight; more decompositions exist.
