Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598042, here are decompositions:

13 + 31598029 = 31598042
31 + 31598011 = 31598042
109 + 31597933 = 31598042
163 + 31597879 = 31598042
199 + 31597843 = 31598042
241 + 31597801 = 31598042
313 + 31597729 = 31598042
349 + 31597693 = 31598042

Showing the first eight; more decompositions exist.
