Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597450, here are decompositions:

83 + 31597367 = 31597450
113 + 31597337 = 31597450
167 + 31597283 = 31597450
197 + 31597253 = 31597450
251 + 31597199 = 31597450
419 + 31597031 = 31597450
569 + 31596881 = 31597450
593 + 31596857 = 31597450

Showing the first eight; more decompositions exist.
