Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606452, here are decompositions:

23 + 31606429 = 31606452
29 + 31606423 = 31606452
41 + 31606411 = 31606452
71 + 31606381 = 31606452
79 + 31606373 = 31606452
83 + 31606369 = 31606452
109 + 31606343 = 31606452
113 + 31606339 = 31606452

Showing the first eight; more decompositions exist.
