Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593026, here are decompositions:

43 + 31592983 = 31593026
67 + 31592959 = 31593026
79 + 31592947 = 31593026
103 + 31592923 = 31593026
193 + 31592833 = 31593026
229 + 31592797 = 31593026
349 + 31592677 = 31593026
769 + 31592257 = 31593026

Showing the first eight; more decompositions exist.
