Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031664, here are decompositions:

31 + 1031633 = 1031664
41 + 1031623 = 1031664
71 + 1031593 = 1031664
103 + 1031561 = 1031664
131 + 1031533 = 1031664
157 + 1031507 = 1031664
181 + 1031483 = 1031664
233 + 1031431 = 1031664

Showing the first eight; more decompositions exist.
