Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561996, here are decompositions:

13 + 561983 = 561996
23 + 561973 = 561996
53 + 561943 = 561996
73 + 561923 = 561996
79 + 561917 = 561996
89 + 561907 = 561996
157 + 561839 = 561996
167 + 561829 = 561996

Showing the first eight; more decompositions exist.
