Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506084, here are decompositions:

13 + 31506071 = 31506084
23 + 31506061 = 31506084
53 + 31506031 = 31506084
101 + 31505983 = 31506084
157 + 31505927 = 31506084
163 + 31505921 = 31506084
241 + 31505843 = 31506084
263 + 31505821 = 31506084

Showing the first eight; more decompositions exist.
