Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598632, here are decompositions:

41 + 31598591 = 31598632
89 + 31598543 = 31598632
113 + 31598519 = 31598632
173 + 31598459 = 31598632
251 + 31598381 = 31598632
269 + 31598363 = 31598632
311 + 31598321 = 31598632
353 + 31598279 = 31598632

Showing the first eight; more decompositions exist.
