Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042256, here are decompositions:

13 + 1042243 = 1042256
73 + 1042183 = 1042256
157 + 1042099 = 1042256
307 + 1041949 = 1042256
337 + 1041919 = 1042256
349 + 1041907 = 1042256
367 + 1041889 = 1042256
433 + 1041823 = 1042256

Showing the first eight; more decompositions exist.
