Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027972, here are decompositions:

3 + 1027969 = 1027972
41 + 1027931 = 1027972
89 + 1027883 = 1027972
131 + 1027841 = 1027972
173 + 1027799 = 1027972
233 + 1027739 = 1027972
269 + 1027703 = 1027972
293 + 1027679 = 1027972

Showing the first eight; more decompositions exist.
