Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102418, here are decompositions:

11 + 102407 = 102418
59 + 102359 = 102418
89 + 102329 = 102418
101 + 102317 = 102418
167 + 102251 = 102418
227 + 102191 = 102418
257 + 102161 = 102418
269 + 102149 = 102418

Showing the first eight; more decompositions exist.
