Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506526, here are decompositions:

3 + 31506523 = 31506526
5 + 31506521 = 31506526
47 + 31506479 = 31506526
83 + 31506443 = 31506526
89 + 31506437 = 31506526
167 + 31506359 = 31506526
173 + 31506353 = 31506526
263 + 31506263 = 31506526

Showing the first eight; more decompositions exist.
