Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584794, here are decompositions:

37 + 31584757 = 31584794
97 + 31584697 = 31584794
127 + 31584667 = 31584794
181 + 31584613 = 31584794
193 + 31584601 = 31584794
271 + 31584523 = 31584794
313 + 31584481 = 31584794
337 + 31584457 = 31584794

Showing the first eight; more decompositions exist.
