Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023146, here are decompositions:

13 + 1023133 = 1023146
67 + 1023079 = 1023146
79 + 1023067 = 1023146
109 + 1023037 = 1023146
127 + 1023019 = 1023146
277 + 1022869 = 1023146
349 + 1022797 = 1023146
373 + 1022773 = 1023146

Showing the first eight; more decompositions exist.
