Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981852, here are decompositions:

29 + 981823 = 981852
41 + 981811 = 981852
43 + 981809 = 981852
83 + 981769 = 981852
139 + 981713 = 981852
149 + 981703 = 981852
199 + 981653 = 981852
229 + 981623 = 981852

Showing the first eight; more decompositions exist.
