Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746890, here are decompositions:

11 + 8746879 = 8746890
17 + 8746873 = 8746890
29 + 8746861 = 8746890
41 + 8746849 = 8746890
43 + 8746847 = 8746890
71 + 8746819 = 8746890
79 + 8746811 = 8746890
83 + 8746807 = 8746890

Showing the first eight; more decompositions exist.
