Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606434, here are decompositions:

5 + 31606429 = 31606434
11 + 31606423 = 31606434
23 + 31606411 = 31606434
37 + 31606397 = 31606434
47 + 31606387 = 31606434
53 + 31606381 = 31606434
61 + 31606373 = 31606434
103 + 31606331 = 31606434

Showing the first eight; more decompositions exist.
