Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042862, here are decompositions:

13 + 1042849 = 1042862
43 + 1042819 = 1042862
103 + 1042759 = 1042862
181 + 1042681 = 1042862
229 + 1042633 = 1042862
463 + 1042399 = 1042862
619 + 1042243 = 1042862
739 + 1042123 = 1042862

Showing the first eight; more decompositions exist.
