Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981482, here are decompositions:

31 + 981451 = 981482
43 + 981439 = 981482
109 + 981373 = 981482
163 + 981319 = 981482
181 + 981301 = 981482
193 + 981289 = 981482
199 + 981283 = 981482
211 + 981271 = 981482

Showing the first eight; more decompositions exist.
