Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594542, here are decompositions:

41 + 31594501 = 31594542
53 + 31594489 = 31594542
79 + 31594463 = 31594542
113 + 31594429 = 31594542
149 + 31594393 = 31594542
191 + 31594351 = 31594542
211 + 31594331 = 31594542
233 + 31594309 = 31594542

Showing the first eight; more decompositions exist.
