Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045664, here are decompositions:

13 + 1045651 = 1045664
31 + 1045633 = 1045664
43 + 1045621 = 1045664
157 + 1045507 = 1045664
241 + 1045423 = 1045664
271 + 1045393 = 1045664
541 + 1045123 = 1045664
547 + 1045117 = 1045664

Showing the first eight; more decompositions exist.
