Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598582, here are decompositions:

61 + 31598521 = 31598582
163 + 31598419 = 31598582
181 + 31598401 = 31598582
229 + 31598353 = 31598582
283 + 31598299 = 31598582
439 + 31598143 = 31598582
571 + 31598011 = 31598582
709 + 31597873 = 31598582

Showing the first eight; more decompositions exist.
