Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593344, here are decompositions:

31 + 31593313 = 31593344
37 + 31593307 = 31593344
151 + 31593193 = 31593344
313 + 31593031 = 31593344
373 + 31592971 = 31593344
397 + 31592947 = 31593344
421 + 31592923 = 31593344
547 + 31592797 = 31593344

Showing the first eight; more decompositions exist.
