Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986642, here are decompositions:

43 + 986599 = 986642
61 + 986581 = 986642
73 + 986569 = 986642
79 + 986563 = 986642
109 + 986533 = 986642
499 + 986143 = 986642
541 + 986101 = 986642
571 + 986071 = 986642

Showing the first eight; more decompositions exist.
