Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594612, here are decompositions:

3 + 31594609 = 31594612
29 + 31594583 = 31594612
59 + 31594553 = 31594612
149 + 31594463 = 31594612
191 + 31594421 = 31594612
239 + 31594373 = 31594612
281 + 31594331 = 31594612
419 + 31594193 = 31594612

Showing the first eight; more decompositions exist.
