Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496356, here are decompositions:

137 + 31496219 = 31496356
233 + 31496123 = 31496356
257 + 31496099 = 31496356
509 + 31495847 = 31496356
599 + 31495757 = 31496356
839 + 31495517 = 31496356
863 + 31495493 = 31496356
887 + 31495469 = 31496356

Showing the first eight; more decompositions exist.
