Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103918, here are decompositions:

5 + 103913 = 103918
29 + 103889 = 103918
107 + 103811 = 103918
131 + 103787 = 103918
149 + 103769 = 103918
389 + 103529 = 103918
461 + 103457 = 103918
467 + 103451 = 103918

Showing the first eight; more decompositions exist.
