Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596236, here are decompositions:

43 + 31596193 = 31596236
73 + 31596163 = 31596236
109 + 31596127 = 31596236
229 + 31596007 = 31596236
307 + 31595929 = 31596236
367 + 31595869 = 31596236
643 + 31595593 = 31596236
769 + 31595467 = 31596236

Showing the first eight; more decompositions exist.
