Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591058, here are decompositions:

67 + 31590991 = 31591058
127 + 31590931 = 31591058
151 + 31590907 = 31591058
181 + 31590877 = 31591058
211 + 31590847 = 31591058
409 + 31590649 = 31591058
487 + 31590571 = 31591058
571 + 31590487 = 31591058

Showing the first eight; more decompositions exist.
