Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981452, here are decompositions:

13 + 981439 = 981452
61 + 981391 = 981452
79 + 981373 = 981452
151 + 981301 = 981452
163 + 981289 = 981452
181 + 981271 = 981452
211 + 981241 = 981452
313 + 981139 = 981452

Showing the first eight; more decompositions exist.
