Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598626, here are decompositions:

83 + 31598543 = 31598626
89 + 31598537 = 31598626
107 + 31598519 = 31598626
113 + 31598513 = 31598626
167 + 31598459 = 31598626
263 + 31598363 = 31598626
347 + 31598279 = 31598626
359 + 31598267 = 31598626

Showing the first eight; more decompositions exist.
