Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051972, here are decompositions:

11 + 1051961 = 1051972
23 + 1051949 = 1051972
59 + 1051913 = 1051972
83 + 1051889 = 1051972
191 + 1051781 = 1051972
263 + 1051709 = 1051972
353 + 1051619 = 1051972
401 + 1051571 = 1051972

Showing the first eight; more decompositions exist.
