Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031372, here are decompositions:

73 + 1031299 = 1031372
211 + 1031161 = 1031372
379 + 1030993 = 1031372
421 + 1030951 = 1031372
439 + 1030933 = 1031372
499 + 1030873 = 1031372
541 + 1030831 = 1031372
571 + 1030801 = 1031372

Showing the first eight; more decompositions exist.
