Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536532, here are decompositions:

3 + 31536529 = 31536532
11 + 31536521 = 31536532
149 + 31536383 = 31536532
173 + 31536359 = 31536532
179 + 31536353 = 31536532
239 + 31536293 = 31536532
431 + 31536101 = 31536532
479 + 31536053 = 31536532

Showing the first eight; more decompositions exist.
