Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582904, here are decompositions:

7 + 31582897 = 31582904
13 + 31582891 = 31582904
127 + 31582777 = 31582904
271 + 31582633 = 31582904
277 + 31582627 = 31582904
373 + 31582531 = 31582904
433 + 31582471 = 31582904
487 + 31582417 = 31582904

Showing the first eight; more decompositions exist.
