Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598516, here are decompositions:

3 + 31598513 = 31598516
67 + 31598449 = 31598516
97 + 31598419 = 31598516
139 + 31598377 = 31598516
163 + 31598353 = 31598516
277 + 31598239 = 31598516
337 + 31598179 = 31598516
373 + 31598143 = 31598516

Showing the first eight; more decompositions exist.
