Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940978, here are decompositions:

29 + 940949 = 940978
47 + 940931 = 940978
89 + 940889 = 940978
107 + 940871 = 940978
149 + 940829 = 940978
191 + 940787 = 940978
197 + 940781 = 940978
239 + 940739 = 940978

Showing the first eight; more decompositions exist.
