Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593500, here are decompositions:

109 + 31593391 = 31593500
157 + 31593343 = 31593500
193 + 31593307 = 31593500
307 + 31593193 = 31593500
541 + 31592959 = 31593500
577 + 31592923 = 31593500
691 + 31592809 = 31593500
727 + 31592773 = 31593500

Showing the first eight; more decompositions exist.
