Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586396, here are decompositions:

19 + 31586377 = 31586396
109 + 31586287 = 31586396
139 + 31586257 = 31586396
337 + 31586059 = 31586396
433 + 31585963 = 31586396
547 + 31585849 = 31586396
613 + 31585783 = 31586396
619 + 31585777 = 31586396

Showing the first eight; more decompositions exist.
