Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057890, here are decompositions:

7 + 1057883 = 1057890
11 + 1057879 = 1057890
37 + 1057853 = 1057890
59 + 1057831 = 1057890
83 + 1057807 = 1057890
109 + 1057781 = 1057890
137 + 1057753 = 1057890
149 + 1057741 = 1057890

Showing the first eight; more decompositions exist.
