Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505496, here are decompositions:

7 + 31505489 = 31505496
23 + 31505473 = 31505496
37 + 31505459 = 31505496
53 + 31505443 = 31505496
109 + 31505387 = 31505496
137 + 31505359 = 31505496
163 + 31505333 = 31505496
167 + 31505329 = 31505496

Showing the first eight; more decompositions exist.
