Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594582, here are decompositions:

3 + 31594579 = 31594582
29 + 31594553 = 31594582
251 + 31594331 = 31594582
311 + 31594271 = 31594582
389 + 31594193 = 31594582
419 + 31594163 = 31594582
431 + 31594151 = 31594582
449 + 31594133 = 31594582

Showing the first eight; more decompositions exist.
