Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025402, here are decompositions:

19 + 1025383 = 1025402
163 + 1025239 = 1025402
193 + 1025209 = 1025402
199 + 1025203 = 1025402
241 + 1025161 = 1025402
283 + 1025119 = 1025402
373 + 1025029 = 1025402
439 + 1024963 = 1025402

Showing the first eight; more decompositions exist.
