Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051978, here are decompositions:

17 + 1051961 = 1051978
29 + 1051949 = 1051978
89 + 1051889 = 1051978
131 + 1051847 = 1051978
149 + 1051829 = 1051978
167 + 1051811 = 1051978
197 + 1051781 = 1051978
269 + 1051709 = 1051978

Showing the first eight; more decompositions exist.
