Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496584, here are decompositions:

11 + 31496573 = 31496584
17 + 31496567 = 31496584
47 + 31496537 = 31496584
167 + 31496417 = 31496584
263 + 31496321 = 31496584
443 + 31496141 = 31496584
461 + 31496123 = 31496584
557 + 31496027 = 31496584

Showing the first eight; more decompositions exist.
