Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495726, here are decompositions:

137 + 31495589 = 31495726
233 + 31495493 = 31495726
257 + 31495469 = 31495726
263 + 31495463 = 31495726
359 + 31495367 = 31495726
569 + 31495157 = 31495726
617 + 31495109 = 31495726
683 + 31495043 = 31495726

Showing the first eight; more decompositions exist.
