Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506534, here are decompositions:

5 + 31506529 = 31506534
11 + 31506523 = 31506534
13 + 31506521 = 31506534
23 + 31506511 = 31506534
97 + 31506437 = 31506534
113 + 31506421 = 31506534
167 + 31506367 = 31506534
181 + 31506353 = 31506534

Showing the first eight; more decompositions exist.
