Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011972, here are decompositions:

11 + 1011961 = 1011972
29 + 1011943 = 1011972
79 + 1011893 = 1011972
83 + 1011889 = 1011972
173 + 1011799 = 1011972
193 + 1011779 = 1011972
223 + 1011749 = 1011972
239 + 1011733 = 1011972

Showing the first eight; more decompositions exist.
