Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496662, here are decompositions:

89 + 31496573 = 31496662
173 + 31496489 = 31496662
233 + 31496429 = 31496662
293 + 31496369 = 31496662
401 + 31496261 = 31496662
443 + 31496219 = 31496662
521 + 31496141 = 31496662
563 + 31496099 = 31496662

Showing the first eight; more decompositions exist.
