Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042802, here are decompositions:

3 + 1042799 = 1042802
43 + 1042759 = 1042802
109 + 1042693 = 1042802
193 + 1042609 = 1042802
283 + 1042519 = 1042802
421 + 1042381 = 1042802
433 + 1042369 = 1042802
619 + 1042183 = 1042802

Showing the first eight; more decompositions exist.
