Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598450, here are decompositions:

31 + 31598419 = 31598450
73 + 31598377 = 31598450
97 + 31598353 = 31598450
151 + 31598299 = 31598450
211 + 31598239 = 31598450
223 + 31598227 = 31598450
271 + 31598179 = 31598450
307 + 31598143 = 31598450

Showing the first eight; more decompositions exist.
