Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606684, here are decompositions:

3 + 31606681 = 31606684
17 + 31606667 = 31606684
23 + 31606661 = 31606684
41 + 31606643 = 31606684
101 + 31606583 = 31606684
167 + 31606517 = 31606684
191 + 31606493 = 31606684
311 + 31606373 = 31606684

Showing the first eight; more decompositions exist.
