Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601396, here are decompositions:

3 + 31601393 = 31601396
37 + 31601359 = 31601396
193 + 31601203 = 31601396
313 + 31601083 = 31601396
373 + 31601023 = 31601396
439 + 31600957 = 31601396
613 + 31600783 = 31601396
643 + 31600753 = 31601396

Showing the first eight; more decompositions exist.
