Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495598, here are decompositions:

7 + 31495591 = 31495598
97 + 31495501 = 31495598
151 + 31495447 = 31495598
181 + 31495417 = 31495598
241 + 31495357 = 31495598
619 + 31494979 = 31495598
661 + 31494937 = 31495598
691 + 31494907 = 31495598

Showing the first eight; more decompositions exist.
