Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598126, here are decompositions:

97 + 31598029 = 31598126
139 + 31597987 = 31598126
193 + 31597933 = 31598126
199 + 31597927 = 31598126
283 + 31597843 = 31598126
349 + 31597777 = 31598126
397 + 31597729 = 31598126
409 + 31597717 = 31598126

Showing the first eight; more decompositions exist.
