Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051430, here are decompositions:

7 + 1051423 = 1051430
13 + 1051417 = 1051430
97 + 1051333 = 1051430
139 + 1051291 = 1051430
277 + 1051153 = 1051430
283 + 1051147 = 1051430
349 + 1051081 = 1051430
379 + 1051051 = 1051430

Showing the first eight; more decompositions exist.
