Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594654, here are decompositions:

41 + 31594613 = 31594654
71 + 31594583 = 31594654
101 + 31594553 = 31594654
107 + 31594547 = 31594654
191 + 31594463 = 31594654
233 + 31594421 = 31594654
281 + 31594373 = 31594654
383 + 31594271 = 31594654

Showing the first eight; more decompositions exist.
