Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603834, here are decompositions:

5 + 31603829 = 31603834
83 + 31603751 = 31603834
113 + 31603721 = 31603834
191 + 31603643 = 31603834
257 + 31603577 = 31603834
281 + 31603553 = 31603834
347 + 31603487 = 31603834
467 + 31603367 = 31603834

Showing the first eight; more decompositions exist.
