Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510670, here are decompositions:

13 + 31510657 = 31510670
43 + 31510627 = 31510670
67 + 31510603 = 31510670
97 + 31510573 = 31510670
109 + 31510561 = 31510670
181 + 31510489 = 31510670
211 + 31510459 = 31510670
223 + 31510447 = 31510670

Showing the first eight; more decompositions exist.
