Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522286, here are decompositions:

43 + 31522243 = 31522286
67 + 31522219 = 31522286
79 + 31522207 = 31522286
157 + 31522129 = 31522286
307 + 31521979 = 31522286
457 + 31521829 = 31522286
547 + 31521739 = 31522286
613 + 31521673 = 31522286

Showing the first eight; more decompositions exist.
