Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031478, here are decompositions:

17 + 1031461 = 1031478
31 + 1031447 = 1031478
47 + 1031431 = 1031478
67 + 1031411 = 1031478
79 + 1031399 = 1031478
131 + 1031347 = 1031478
179 + 1031299 = 1031478
197 + 1031281 = 1031478

Showing the first eight; more decompositions exist.
