Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031388, here are decompositions:

31 + 1031357 = 1031388
41 + 1031347 = 1031388
79 + 1031309 = 1031388
89 + 1031299 = 1031388
97 + 1031291 = 1031388
107 + 1031281 = 1031388
109 + 1031279 = 1031388
157 + 1031231 = 1031388

Showing the first eight; more decompositions exist.
