Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593428, here are decompositions:

37 + 31593391 = 31593428
331 + 31593097 = 31593428
397 + 31593031 = 31593428
457 + 31592971 = 31593428
619 + 31592809 = 31593428
631 + 31592797 = 31593428
751 + 31592677 = 31593428
787 + 31592641 = 31593428

Showing the first eight; more decompositions exist.
