Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575696, here are decompositions:

29 + 31575667 = 31575696
43 + 31575653 = 31575696
59 + 31575637 = 31575696
197 + 31575499 = 31575696
227 + 31575469 = 31575696
263 + 31575433 = 31575696
359 + 31575337 = 31575696
463 + 31575233 = 31575696

Showing the first eight; more decompositions exist.
