Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047972, here are decompositions:

11 + 1047961 = 1047972
31 + 1047941 = 1047972
43 + 1047929 = 1047972
89 + 1047883 = 1047972
113 + 1047859 = 1047972
131 + 1047841 = 1047972
139 + 1047833 = 1047972
151 + 1047821 = 1047972

Showing the first eight; more decompositions exist.
