Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945028, here are decompositions:

41 + 944987 = 945028
59 + 944969 = 945028
131 + 944897 = 945028
251 + 944777 = 945028
311 + 944717 = 945028
317 + 944711 = 945028
419 + 944609 = 945028
449 + 944579 = 945028

Showing the first eight; more decompositions exist.
