Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945146, here are decompositions:

3 + 945143 = 945146
43 + 945103 = 945146
109 + 945037 = 945146
193 + 944953 = 945146
313 + 944833 = 945146
373 + 944773 = 945146
457 + 944689 = 945146
487 + 944659 = 945146

Showing the first eight; more decompositions exist.
