Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142926, here are decompositions:

19 + 142907 = 142926
23 + 142903 = 142926
29 + 142897 = 142926
53 + 142873 = 142926
59 + 142867 = 142926
89 + 142837 = 142926
127 + 142799 = 142926
137 + 142789 = 142926

Showing the first eight; more decompositions exist.
