Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599474, here are decompositions:

43 + 31599431 = 31599474
167 + 31599307 = 31599474
227 + 31599247 = 31599474
281 + 31599193 = 31599474
317 + 31599157 = 31599474
373 + 31599101 = 31599474
521 + 31598953 = 31599474
541 + 31598933 = 31599474

Showing the first eight; more decompositions exist.
