Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598412, here are decompositions:

11 + 31598401 = 31598412
31 + 31598381 = 31598412
59 + 31598353 = 31598412
113 + 31598299 = 31598412
151 + 31598261 = 31598412
173 + 31598239 = 31598412
199 + 31598213 = 31598412
211 + 31598201 = 31598412

Showing the first eight; more decompositions exist.
