Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662890, here are decompositions:

23 + 8662867 = 8662890
31 + 8662859 = 8662890
37 + 8662853 = 8662890
59 + 8662831 = 8662890
79 + 8662811 = 8662890
83 + 8662807 = 8662890
107 + 8662783 = 8662890
139 + 8662751 = 8662890

Showing the first eight; more decompositions exist.
