Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497164, here are decompositions:

7 + 31497157 = 31497164
31 + 31497133 = 31497164
37 + 31497127 = 31497164
157 + 31497007 = 31497164
163 + 31497001 = 31497164
337 + 31496827 = 31497164
373 + 31496791 = 31497164
487 + 31496677 = 31497164

Showing the first eight; more decompositions exist.
