Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496164, here are decompositions:

3 + 31496161 = 31496164
23 + 31496141 = 31496164
41 + 31496123 = 31496164
107 + 31496057 = 31496164
137 + 31496027 = 31496164
317 + 31495847 = 31496164
431 + 31495733 = 31496164
503 + 31495661 = 31496164

Showing the first eight; more decompositions exist.
