Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598012, here are decompositions:

3 + 31598009 = 31598012
79 + 31597933 = 31598012
139 + 31597873 = 31598012
211 + 31597801 = 31598012
283 + 31597729 = 31598012
373 + 31597639 = 31598012
409 + 31597603 = 31598012
463 + 31597549 = 31598012

Showing the first eight; more decompositions exist.
