Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606846, here are decompositions:

17 + 31606829 = 31606846
149 + 31606697 = 31606846
179 + 31606667 = 31606846
263 + 31606583 = 31606846
317 + 31606529 = 31606846
347 + 31606499 = 31606846
353 + 31606493 = 31606846
449 + 31606397 = 31606846

Showing the first eight; more decompositions exist.
