Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031408, here are decompositions:

61 + 1031347 = 1031408
109 + 1031299 = 1031408
127 + 1031281 = 1031408
271 + 1031137 = 1031408
421 + 1030987 = 1031408
457 + 1030951 = 1031408
541 + 1030867 = 1031408
577 + 1030831 = 1031408

Showing the first eight; more decompositions exist.
