Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606404, here are decompositions:

7 + 31606397 = 31606404
17 + 31606387 = 31606404
23 + 31606381 = 31606404
31 + 31606373 = 31606404
61 + 31606343 = 31606404
73 + 31606331 = 31606404
107 + 31606297 = 31606404
127 + 31606277 = 31606404

Showing the first eight; more decompositions exist.
