Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945040, here are decompositions:

3 + 945037 = 945040
53 + 944987 = 945040
71 + 944969 = 945040
167 + 944873 = 945040
263 + 944777 = 945040
311 + 944729 = 945040
353 + 944687 = 945040
389 + 944651 = 945040

Showing the first eight; more decompositions exist.
