Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495876, here are decompositions:

17 + 31495859 = 31495876
29 + 31495847 = 31495876
353 + 31495523 = 31495876
359 + 31495517 = 31495876
383 + 31495493 = 31495876
509 + 31495367 = 31495876
677 + 31495199 = 31495876
719 + 31495157 = 31495876

Showing the first eight; more decompositions exist.
