Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541552, here are decompositions:

43 + 31541509 = 31541552
103 + 31541449 = 31541552
151 + 31541401 = 31541552
193 + 31541359 = 31541552
271 + 31541281 = 31541552
283 + 31541269 = 31541552
373 + 31541179 = 31541552
379 + 31541173 = 31541552

Showing the first eight; more decompositions exist.
