Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705148, here are decompositions:

37 + 8705111 = 8705148
61 + 8705087 = 8705148
71 + 8705077 = 8705148
79 + 8705069 = 8705148
97 + 8705051 = 8705148
107 + 8705041 = 8705148
139 + 8705009 = 8705148
167 + 8704981 = 8705148

Showing the first eight; more decompositions exist.
