Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497176, here are decompositions:

19 + 31497157 = 31497176
37 + 31497139 = 31497176
43 + 31497133 = 31497176
199 + 31496977 = 31497176
229 + 31496947 = 31497176
313 + 31496863 = 31497176
349 + 31496827 = 31497176
367 + 31496809 = 31497176

Showing the first eight; more decompositions exist.
