Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021438, here are decompositions:

71 + 1021367 = 1021438
107 + 1021331 = 1021438
137 + 1021301 = 1021438
149 + 1021289 = 1021438
167 + 1021271 = 1021438
179 + 1021259 = 1021438
239 + 1021199 = 1021438
281 + 1021157 = 1021438

Showing the first eight; more decompositions exist.
