Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593338, here are decompositions:

31 + 31593307 = 31593338
229 + 31593109 = 31593338
241 + 31593097 = 31593338
307 + 31593031 = 31593338
367 + 31592971 = 31593338
379 + 31592959 = 31593338
541 + 31592797 = 31593338
577 + 31592761 = 31593338

Showing the first eight; more decompositions exist.
