Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103678, here are decompositions:

59 + 103619 = 103678
101 + 103577 = 103678
149 + 103529 = 103678
167 + 103511 = 103678
227 + 103451 = 103678
257 + 103421 = 103678
269 + 103409 = 103678
359 + 103319 = 103678

Showing the first eight; more decompositions exist.
