Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594536, here are decompositions:

47 + 31594489 = 31594536
73 + 31594463 = 31594536
107 + 31594429 = 31594536
137 + 31594399 = 31594536
163 + 31594373 = 31594536
227 + 31594309 = 31594536
263 + 31594273 = 31594536
373 + 31594163 = 31594536

Showing the first eight; more decompositions exist.
