Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497694, here are decompositions:

23 + 31497671 = 31497694
167 + 31497527 = 31497694
227 + 31497467 = 31497694
233 + 31497461 = 31497694
251 + 31497443 = 31497694
353 + 31497341 = 31497694
401 + 31497293 = 31497694
443 + 31497251 = 31497694

Showing the first eight; more decompositions exist.
