Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496160, here are decompositions:

19 + 31496141 = 31496160
37 + 31496123 = 31496160
41 + 31496119 = 31496160
61 + 31496099 = 31496160
103 + 31496057 = 31496160
149 + 31496011 = 31496160
181 + 31495979 = 31496160
211 + 31495949 = 31496160

Showing the first eight; more decompositions exist.
