Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103618, here are decompositions:

5 + 103613 = 103618
41 + 103577 = 103618
89 + 103529 = 103618
107 + 103511 = 103618
167 + 103451 = 103618
197 + 103421 = 103618
227 + 103391 = 103618
269 + 103349 = 103618

Showing the first eight; more decompositions exist.
