Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598576, here are decompositions:

127 + 31598449 = 31598576
157 + 31598419 = 31598576
199 + 31598377 = 31598576
223 + 31598353 = 31598576
277 + 31598299 = 31598576
337 + 31598239 = 31598576
349 + 31598227 = 31598576
397 + 31598179 = 31598576

Showing the first eight; more decompositions exist.
