Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045868, here are decompositions:

67 + 1045801 = 1045868
139 + 1045729 = 1045868
457 + 1045411 = 1045868
547 + 1045321 = 1045868
631 + 1045237 = 1045868
739 + 1045129 = 1045868
751 + 1045117 = 1045868
757 + 1045111 = 1045868

Showing the first eight; more decompositions exist.
