Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031218, here are decompositions:

29 + 1031189 = 1031218
101 + 1031117 = 1031218
137 + 1031081 = 1031218
269 + 1030949 = 1031218
401 + 1030817 = 1031218
431 + 1030787 = 1031218
467 + 1030751 = 1031218
479 + 1030739 = 1031218

Showing the first eight; more decompositions exist.
