Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593008, here are decompositions:

37 + 31592971 = 31593008
61 + 31592947 = 31593008
199 + 31592809 = 31593008
211 + 31592797 = 31593008
229 + 31592779 = 31593008
331 + 31592677 = 31593008
367 + 31592641 = 31593008
409 + 31592599 = 31593008

Showing the first eight; more decompositions exist.
