Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042890, here are decompositions:

29 + 1042861 = 1042890
41 + 1042849 = 1042890
53 + 1042837 = 1042890
61 + 1042829 = 1042890
71 + 1042819 = 1042890
109 + 1042781 = 1042890
131 + 1042759 = 1042890
157 + 1042733 = 1042890

Showing the first eight; more decompositions exist.
