Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705142, here are decompositions:

31 + 8705111 = 8705142
73 + 8705069 = 8705142
101 + 8705041 = 8705142
109 + 8705033 = 8705142
113 + 8705029 = 8705142
163 + 8704979 = 8705142
191 + 8704951 = 8705142
233 + 8704909 = 8705142

Showing the first eight; more decompositions exist.
