Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496470, here are decompositions:

29 + 31496441 = 31496470
41 + 31496429 = 31496470
53 + 31496417 = 31496470
101 + 31496369 = 31496470
149 + 31496321 = 31496470
251 + 31496219 = 31496470
347 + 31496123 = 31496470
443 + 31496027 = 31496470

Showing the first eight; more decompositions exist.
