Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598668, here are decompositions:

131 + 31598537 = 31598668
149 + 31598519 = 31598668
251 + 31598417 = 31598668
347 + 31598321 = 31598668
389 + 31598279 = 31598668
401 + 31598267 = 31598668
467 + 31598201 = 31598668
641 + 31598027 = 31598668

Showing the first eight; more decompositions exist.
