Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103018, here are decompositions:

11 + 103007 = 103018
17 + 103001 = 103018
89 + 102929 = 103018
107 + 102911 = 103018
137 + 102881 = 103018
257 + 102761 = 103018
317 + 102701 = 103018
431 + 102587 = 103018

Showing the first eight; more decompositions exist.
