Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593494, here are decompositions:

3 + 31593491 = 31593494
103 + 31593391 = 31593494
151 + 31593343 = 31593494
181 + 31593313 = 31593494
241 + 31593253 = 31593494
397 + 31593097 = 31593494
463 + 31593031 = 31593494
523 + 31592971 = 31593494

Showing the first eight; more decompositions exist.
