Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604984, here are decompositions:

181 + 31604803 = 31604984
241 + 31604743 = 31604984
337 + 31604647 = 31604984
373 + 31604611 = 31604984
487 + 31604497 = 31604984
601 + 31604383 = 31604984
613 + 31604371 = 31604984
643 + 31604341 = 31604984

Showing the first eight; more decompositions exist.
