Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606436, here are decompositions:

7 + 31606429 = 31606436
13 + 31606423 = 31606436
67 + 31606369 = 31606436
97 + 31606339 = 31606436
139 + 31606297 = 31606436
157 + 31606279 = 31606436
349 + 31606087 = 31606436
523 + 31605913 = 31606436

Showing the first eight; more decompositions exist.
