Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945428, here are decompositions:

19 + 945409 = 945428
31 + 945397 = 945428
37 + 945391 = 945428
61 + 945367 = 945428
79 + 945349 = 945428
97 + 945331 = 945428
139 + 945289 = 945428
277 + 945151 = 945428

Showing the first eight; more decompositions exist.
