Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532544, here are decompositions:

5 + 31532539 = 31532544
23 + 31532521 = 31532544
37 + 31532507 = 31532544
47 + 31532497 = 31532544
67 + 31532477 = 31532544
107 + 31532437 = 31532544
191 + 31532353 = 31532544
283 + 31532261 = 31532544

Showing the first eight; more decompositions exist.
