Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606724, here are decompositions:

13 + 31606711 = 31606724
43 + 31606681 = 31606724
67 + 31606657 = 31606724
73 + 31606651 = 31606724
181 + 31606543 = 31606724
313 + 31606411 = 31606724
337 + 31606387 = 31606724
463 + 31606261 = 31606724

Showing the first eight; more decompositions exist.
