Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497274, here are decompositions:

23 + 31497251 = 31497274
191 + 31497083 = 31497274
311 + 31496963 = 31497274
317 + 31496957 = 31497274
353 + 31496921 = 31497274
401 + 31496873 = 31497274
491 + 31496783 = 31497274
701 + 31496573 = 31497274

Showing the first eight; more decompositions exist.
