Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019748, here are decompositions:

7 + 1019741 = 1019748
17 + 1019731 = 1019748
19 + 1019729 = 1019748
31 + 1019717 = 1019748
47 + 1019701 = 1019748
61 + 1019687 = 1019748
101 + 1019647 = 1019748
109 + 1019639 = 1019748

Showing the first eight; more decompositions exist.
