Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598630, here are decompositions:

109 + 31598521 = 31598630
181 + 31598449 = 31598630
211 + 31598419 = 31598630
229 + 31598401 = 31598630
277 + 31598353 = 31598630
331 + 31598299 = 31598630
439 + 31598191 = 31598630
487 + 31598143 = 31598630

Showing the first eight; more decompositions exist.
