Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497344, here are decompositions:

3 + 31497341 = 31497344
7 + 31497337 = 31497344
31 + 31497313 = 31497344
61 + 31497283 = 31497344
157 + 31497187 = 31497344
211 + 31497133 = 31497344
337 + 31497007 = 31497344
367 + 31496977 = 31497344

Showing the first eight; more decompositions exist.
