Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541882, here are decompositions:

13 + 31541869 = 31541882
223 + 31541659 = 31541882
271 + 31541611 = 31541882
313 + 31541569 = 31541882
373 + 31541509 = 31541882
433 + 31541449 = 31541882
523 + 31541359 = 31541882
601 + 31541281 = 31541882

Showing the first eight; more decompositions exist.
