Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594804, here are decompositions:

5 + 31594799 = 31594804
47 + 31594757 = 31594804
113 + 31594691 = 31594804
191 + 31594613 = 31594804
251 + 31594553 = 31594804
257 + 31594547 = 31594804
383 + 31594421 = 31594804
431 + 31594373 = 31594804

Showing the first eight; more decompositions exist.
