Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031406, here are decompositions:

7 + 1031399 = 1031406
59 + 1031347 = 1031406
83 + 1031323 = 1031406
97 + 1031309 = 1031406
107 + 1031299 = 1031406
127 + 1031279 = 1031406
139 + 1031267 = 1031406
269 + 1031137 = 1031406

Showing the first eight; more decompositions exist.
