Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597604, here are decompositions:

97 + 31597507 = 31597604
151 + 31597453 = 31597604
193 + 31597411 = 31597604
373 + 31597231 = 31597604
523 + 31597081 = 31597604
601 + 31597003 = 31597604
607 + 31596997 = 31597604
613 + 31596991 = 31597604

Showing the first eight; more decompositions exist.
