Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594262, here are decompositions:

103 + 31594159 = 31594262
181 + 31594081 = 31594262
199 + 31594063 = 31594262
223 + 31594039 = 31594262
331 + 31593931 = 31594262
499 + 31593763 = 31594262
541 + 31593721 = 31594262
619 + 31593643 = 31594262

Showing the first eight; more decompositions exist.
