Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510766, here are decompositions:

3 + 31510763 = 31510766
13 + 31510753 = 31510766
109 + 31510657 = 31510766
139 + 31510627 = 31510766
163 + 31510603 = 31510766
193 + 31510573 = 31510766
277 + 31510489 = 31510766
307 + 31510459 = 31510766

Showing the first eight; more decompositions exist.
