Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497484, here are decompositions:

17 + 31497467 = 31497484
23 + 31497461 = 31497484
41 + 31497443 = 31497484
131 + 31497353 = 31497484
191 + 31497293 = 31497484
197 + 31497287 = 31497484
233 + 31497251 = 31497484
401 + 31497083 = 31497484

Showing the first eight; more decompositions exist.
