Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991852, here are decompositions:

41 + 991811 = 991852
101 + 991751 = 991852
149 + 991703 = 991852
233 + 991619 = 991852
311 + 991541 = 991852
353 + 991499 = 991852
359 + 991493 = 991852
443 + 991409 = 991852

Showing the first eight; more decompositions exist.
