Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598066, here are decompositions:

37 + 31598029 = 31598066
79 + 31597987 = 31598066
139 + 31597927 = 31598066
193 + 31597873 = 31598066
223 + 31597843 = 31598066
337 + 31597729 = 31598066
349 + 31597717 = 31598066
373 + 31597693 = 31598066

Showing the first eight; more decompositions exist.
