Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495352, here are decompositions:

19 + 31495333 = 31495352
79 + 31495273 = 31495352
139 + 31495213 = 31495352
181 + 31495171 = 31495352
199 + 31495153 = 31495352
349 + 31495003 = 31495352
373 + 31494979 = 31495352
409 + 31494943 = 31495352

Showing the first eight; more decompositions exist.
