Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599158, here are decompositions:

211 + 31598947 = 31599158
271 + 31598887 = 31599158
379 + 31598779 = 31599158
457 + 31598701 = 31599158
709 + 31598449 = 31599158
739 + 31598419 = 31599158
757 + 31598401 = 31599158
859 + 31598299 = 31599158

Showing the first eight; more decompositions exist.
