Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102426, here are decompositions:

17 + 102409 = 102426
19 + 102407 = 102426
29 + 102397 = 102426
59 + 102367 = 102426
67 + 102359 = 102426
89 + 102337 = 102426
97 + 102329 = 102426
109 + 102317 = 102426

Showing the first eight; more decompositions exist.
