Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496026, here are decompositions:

47 + 31495979 = 31496026
167 + 31495859 = 31496026
179 + 31495847 = 31496026
269 + 31495757 = 31496026
293 + 31495733 = 31496026
503 + 31495523 = 31496026
509 + 31495517 = 31496026
557 + 31495469 = 31496026

Showing the first eight; more decompositions exist.
