Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018342, here are decompositions:

5 + 1018337 = 1018342
29 + 1018313 = 1018342
41 + 1018301 = 1018342
71 + 1018271 = 1018342
89 + 1018253 = 1018342
233 + 1018109 = 1018342
251 + 1018091 = 1018342
383 + 1017959 = 1018342

Showing the first eight; more decompositions exist.
