Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000438, here are decompositions:

11 + 1000427 = 1000438
29 + 1000409 = 1000438
41 + 1000397 = 1000438
71 + 1000367 = 1000438
149 + 1000289 = 1000438
227 + 1000211 = 1000438
239 + 1000199 = 1000438
251 + 1000187 = 1000438

Showing the first eight; more decompositions exist.
