Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496262, here are decompositions:

41 + 31496221 = 31496262
43 + 31496219 = 31496262
53 + 31496209 = 31496262
89 + 31496173 = 31496262
101 + 31496161 = 31496262
139 + 31496123 = 31496262
163 + 31496099 = 31496262
179 + 31496083 = 31496262

Showing the first eight; more decompositions exist.
