Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506532, here are decompositions:

3 + 31506529 = 31506532
11 + 31506521 = 31506532
53 + 31506479 = 31506532
89 + 31506443 = 31506532
173 + 31506359 = 31506532
179 + 31506353 = 31506532
269 + 31506263 = 31506532
359 + 31506173 = 31506532

Showing the first eight; more decompositions exist.
