Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598522, here are decompositions:

3 + 31598519 = 31598522
73 + 31598449 = 31598522
103 + 31598419 = 31598522
223 + 31598299 = 31598522
283 + 31598239 = 31598522
331 + 31598191 = 31598522
379 + 31598143 = 31598522
421 + 31598101 = 31598522

Showing the first eight; more decompositions exist.
