Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593068, here are decompositions:

37 + 31593031 = 31593068
97 + 31592971 = 31593068
109 + 31592959 = 31593068
271 + 31592797 = 31593068
307 + 31592761 = 31593068
601 + 31592467 = 31593068
631 + 31592437 = 31593068
691 + 31592377 = 31593068

Showing the first eight; more decompositions exist.
