Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598362, here are decompositions:

41 + 31598321 = 31598362
83 + 31598279 = 31598362
101 + 31598261 = 31598362
149 + 31598213 = 31598362
353 + 31598009 = 31598362
401 + 31597961 = 31598362
449 + 31597913 = 31598362
569 + 31597793 = 31598362

Showing the first eight; more decompositions exist.
