Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945140, here are decompositions:

37 + 945103 = 945140
103 + 945037 = 945140
109 + 945031 = 945140
211 + 944929 = 945140
241 + 944899 = 945140
283 + 944857 = 945140
307 + 944833 = 945140
337 + 944803 = 945140

Showing the first eight; more decompositions exist.
