Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705904, here are decompositions:

23 + 8705881 = 8705904
43 + 8705861 = 8705904
61 + 8705843 = 8705904
73 + 8705831 = 8705904
101 + 8705803 = 8705904
113 + 8705791 = 8705904
127 + 8705777 = 8705904
131 + 8705773 = 8705904

Showing the first eight; more decompositions exist.
