Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597276, here are decompositions:

23 + 31597253 = 31597276
149 + 31597127 = 31597276
233 + 31597043 = 31597276
353 + 31596923 = 31597276
419 + 31596857 = 31597276
479 + 31596797 = 31597276
563 + 31596713 = 31597276
569 + 31596707 = 31597276

Showing the first eight; more decompositions exist.
