Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586262, here are decompositions:

5 + 31586257 = 31586262
131 + 31586131 = 31586262
283 + 31585979 = 31586262
359 + 31585903 = 31586262
373 + 31585889 = 31586262
439 + 31585823 = 31586262
479 + 31585783 = 31586262
571 + 31585691 = 31586262

Showing the first eight; more decompositions exist.
