Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655890, here are decompositions:

7 + 8655883 = 8655890
13 + 8655877 = 8655890
31 + 8655859 = 8655890
151 + 8655739 = 8655890
157 + 8655733 = 8655890
211 + 8655679 = 8655890
241 + 8655649 = 8655890
433 + 8655457 = 8655890

Showing the first eight; more decompositions exist.
