Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042990, here are decompositions:

29 + 1042961 = 1042990
41 + 1042949 = 1042990
59 + 1042931 = 1042990
89 + 1042901 = 1042990
191 + 1042799 = 1042990
257 + 1042733 = 1042990
281 + 1042709 = 1042990
359 + 1042631 = 1042990

Showing the first eight; more decompositions exist.
