Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594418, here are decompositions:

19 + 31594399 = 31594418
67 + 31594351 = 31594418
109 + 31594309 = 31594418
181 + 31594237 = 31594418
337 + 31594081 = 31594418
379 + 31594039 = 31594418
487 + 31593931 = 31594418
631 + 31593787 = 31594418

Showing the first eight; more decompositions exist.
