Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549852, here are decompositions:

23 + 31549829 = 31549852
53 + 31549799 = 31549852
71 + 31549781 = 31549852
101 + 31549751 = 31549852
263 + 31549589 = 31549852
353 + 31549499 = 31549852
401 + 31549451 = 31549852
449 + 31549403 = 31549852

Showing the first eight; more decompositions exist.
