Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497476, here are decompositions:

7 + 31497469 = 31497476
13 + 31497463 = 31497476
67 + 31497409 = 31497476
139 + 31497337 = 31497476
163 + 31497313 = 31497476
193 + 31497283 = 31497476
337 + 31497139 = 31497476
349 + 31497127 = 31497476

Showing the first eight; more decompositions exist.
