Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496404, here are decompositions:

83 + 31496321 = 31496404
263 + 31496141 = 31496404
281 + 31496123 = 31496404
347 + 31496057 = 31496404
557 + 31495847 = 31496404
647 + 31495757 = 31496404
743 + 31495661 = 31496404
881 + 31495523 = 31496404

Showing the first eight; more decompositions exist.
