Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482904, here are decompositions:

71 + 31482833 = 31482904
83 + 31482821 = 31482904
197 + 31482707 = 31482904
263 + 31482641 = 31482904
317 + 31482587 = 31482904
353 + 31482551 = 31482904
503 + 31482401 = 31482904
647 + 31482257 = 31482904

Showing the first eight; more decompositions exist.
