Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598498, here are decompositions:

79 + 31598419 = 31598498
97 + 31598401 = 31598498
199 + 31598299 = 31598498
271 + 31598227 = 31598498
307 + 31598191 = 31598498
397 + 31598101 = 31598498
487 + 31598011 = 31598498
571 + 31597927 = 31598498

Showing the first eight; more decompositions exist.
