Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018882, here are decompositions:

3 + 1018879 = 1018882
23 + 1018859 = 1018882
71 + 1018811 = 1018882
113 + 1018769 = 1018882
149 + 1018733 = 1018882
173 + 1018709 = 1018882
233 + 1018649 = 1018882
239 + 1018643 = 1018882

Showing the first eight; more decompositions exist.
