Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495298, here are decompositions:

127 + 31495171 = 31495298
151 + 31495147 = 31495298
181 + 31495117 = 31495298
349 + 31494949 = 31495298
379 + 31494919 = 31495298
577 + 31494721 = 31495298
607 + 31494691 = 31495298
619 + 31494679 = 31495298

Showing the first eight; more decompositions exist.
