Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597654, here are decompositions:

3 + 31597651 = 31597654
41 + 31597613 = 31597654
83 + 31597571 = 31597654
113 + 31597541 = 31597654
317 + 31597337 = 31597654
401 + 31597253 = 31597654
503 + 31597151 = 31597654
677 + 31596977 = 31597654

Showing the first eight; more decompositions exist.
