Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025606, here are decompositions:

97 + 1025509 = 1025606
103 + 1025503 = 1025606
163 + 1025443 = 1025606
193 + 1025413 = 1025606
199 + 1025407 = 1025606
223 + 1025383 = 1025606
349 + 1025257 = 1025606
367 + 1025239 = 1025606

Showing the first eight; more decompositions exist.
