Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495376, here are decompositions:

19 + 31495357 = 31495376
43 + 31495333 = 31495376
103 + 31495273 = 31495376
163 + 31495213 = 31495376
223 + 31495153 = 31495376
229 + 31495147 = 31495376
313 + 31495063 = 31495376
373 + 31495003 = 31495376

Showing the first eight; more decompositions exist.
