Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606832, here are decompositions:

3 + 31606829 = 31606832
79 + 31606753 = 31606832
151 + 31606681 = 31606832
181 + 31606651 = 31606832
409 + 31606423 = 31606832
421 + 31606411 = 31606832
463 + 31606369 = 31606832
571 + 31606261 = 31606832

Showing the first eight; more decompositions exist.
