Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598082, here are decompositions:

53 + 31598029 = 31598082
71 + 31598011 = 31598082
73 + 31598009 = 31598082
149 + 31597933 = 31598082
239 + 31597843 = 31598082
281 + 31597801 = 31598082
353 + 31597729 = 31598082
389 + 31597693 = 31598082

Showing the first eight; more decompositions exist.
