Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597084, here are decompositions:

3 + 31597081 = 31597084
41 + 31597043 = 31597084
53 + 31597031 = 31597084
107 + 31596977 = 31597084
227 + 31596857 = 31597084
263 + 31596821 = 31597084
587 + 31596497 = 31597084
647 + 31596437 = 31597084

Showing the first eight; more decompositions exist.
