Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606470, here are decompositions:

41 + 31606429 = 31606470
47 + 31606423 = 31606470
59 + 31606411 = 31606470
73 + 31606397 = 31606470
83 + 31606387 = 31606470
89 + 31606381 = 31606470
97 + 31606373 = 31606470
101 + 31606369 = 31606470

Showing the first eight; more decompositions exist.
