Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606626, here are decompositions:

43 + 31606583 = 31606626
47 + 31606579 = 31606626
67 + 31606559 = 31606626
83 + 31606543 = 31606626
89 + 31606537 = 31606626
97 + 31606529 = 31606626
109 + 31606517 = 31606626
127 + 31606499 = 31606626

Showing the first eight; more decompositions exist.
