Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945018, here are decompositions:

31 + 944987 = 945018
89 + 944929 = 945018
131 + 944887 = 945018
197 + 944821 = 945018
241 + 944777 = 945018
307 + 944711 = 945018
317 + 944701 = 945018
331 + 944687 = 945018

Showing the first eight; more decompositions exist.
