Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598174, here are decompositions:

31 + 31598143 = 31598174
37 + 31598137 = 31598174
73 + 31598101 = 31598174
163 + 31598011 = 31598174
241 + 31597933 = 31598174
331 + 31597843 = 31598174
373 + 31597801 = 31598174
397 + 31597777 = 31598174

Showing the first eight; more decompositions exist.
