Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496174, here are decompositions:

13 + 31496161 = 31496174
163 + 31496011 = 31496174
277 + 31495897 = 31496174
373 + 31495801 = 31496174
421 + 31495753 = 31496174
433 + 31495741 = 31496174
571 + 31495603 = 31496174
673 + 31495501 = 31496174

Showing the first eight; more decompositions exist.
