Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606610, here are decompositions:

31 + 31606579 = 31606610
67 + 31606543 = 31606610
73 + 31606537 = 31606610
181 + 31606429 = 31606610
199 + 31606411 = 31606610
223 + 31606387 = 31606610
229 + 31606381 = 31606610
241 + 31606369 = 31606610

Showing the first eight; more decompositions exist.
