Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593554, here are decompositions:

37 + 31593517 = 31593554
43 + 31593511 = 31593554
163 + 31593391 = 31593554
211 + 31593343 = 31593554
241 + 31593313 = 31593554
457 + 31593097 = 31593554
523 + 31593031 = 31593554
571 + 31592983 = 31593554

Showing the first eight; more decompositions exist.
