Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018412, here are decompositions:

103 + 1018309 = 1018412
211 + 1018201 = 1018412
523 + 1017889 = 1018412
613 + 1017799 = 1018412
631 + 1017781 = 1018412
691 + 1017721 = 1018412
709 + 1017703 = 1018412
739 + 1017673 = 1018412

Showing the first eight; more decompositions exist.
