Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981132, here are decompositions:

41 + 981091 = 981132
59 + 981073 = 981132
71 + 981061 = 981132
83 + 981049 = 981132
109 + 981023 = 981132
211 + 980921 = 981132
223 + 980909 = 981132
233 + 980899 = 981132

Showing the first eight; more decompositions exist.
