Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606446, here are decompositions:

17 + 31606429 = 31606446
23 + 31606423 = 31606446
59 + 31606387 = 31606446
73 + 31606373 = 31606446
103 + 31606343 = 31606446
107 + 31606339 = 31606446
127 + 31606319 = 31606446
149 + 31606297 = 31606446

Showing the first eight; more decompositions exist.
