Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051890, here are decompositions:

11 + 1051879 = 1051890
41 + 1051849 = 1051890
43 + 1051847 = 1051890
61 + 1051829 = 1051890
71 + 1051819 = 1051890
79 + 1051811 = 1051890
101 + 1051789 = 1051890
109 + 1051781 = 1051890

Showing the first eight; more decompositions exist.
