Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520552, here are decompositions:

43 + 31520509 = 31520552
61 + 31520491 = 31520552
73 + 31520479 = 31520552
163 + 31520389 = 31520552
181 + 31520371 = 31520552
199 + 31520353 = 31520552
373 + 31520179 = 31520552
379 + 31520173 = 31520552

Showing the first eight; more decompositions exist.
