Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495606, here are decompositions:

3 + 31495603 = 31495606
5 + 31495601 = 31495606
17 + 31495589 = 31495606
83 + 31495523 = 31495606
89 + 31495517 = 31495606
113 + 31495493 = 31495606
137 + 31495469 = 31495606
239 + 31495367 = 31495606

Showing the first eight; more decompositions exist.
