Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103804, here are decompositions:

3 + 103801 = 103804
17 + 103787 = 103804
101 + 103703 = 103804
191 + 103613 = 103804
227 + 103577 = 103804
251 + 103553 = 103804
293 + 103511 = 103804
347 + 103457 = 103804

Showing the first eight; more decompositions exist.
