Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599058, here are decompositions:

131 + 31598927 = 31599058
149 + 31598909 = 31599058
191 + 31598867 = 31599058
269 + 31598789 = 31599058
389 + 31598669 = 31599058
467 + 31598591 = 31599058
521 + 31598537 = 31599058
599 + 31598459 = 31599058

Showing the first eight; more decompositions exist.
