Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598456, here are decompositions:

7 + 31598449 = 31598456
37 + 31598419 = 31598456
79 + 31598377 = 31598456
103 + 31598353 = 31598456
157 + 31598299 = 31598456
229 + 31598227 = 31598456
277 + 31598179 = 31598456
313 + 31598143 = 31598456

Showing the first eight; more decompositions exist.
