Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031582, here are decompositions:

61 + 1031521 = 1031582
103 + 1031479 = 1031582
151 + 1031431 = 1031582
283 + 1031299 = 1031582
421 + 1031161 = 1031582
463 + 1031119 = 1031582
631 + 1030951 = 1031582
709 + 1030873 = 1031582

Showing the first eight; more decompositions exist.
