Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048890, here are decompositions:

13 + 1048877 = 1048890
23 + 1048867 = 1048890
43 + 1048847 = 1048890
53 + 1048837 = 1048890
61 + 1048829 = 1048890
83 + 1048807 = 1048890
97 + 1048793 = 1048890
107 + 1048783 = 1048890

Showing the first eight; more decompositions exist.
