Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047890, here are decompositions:

3 + 1047887 = 1047890
7 + 1047883 = 1047890
31 + 1047859 = 1047890
127 + 1047763 = 1047890
139 + 1047751 = 1047890
199 + 1047691 = 1047890
223 + 1047667 = 1047890
241 + 1047649 = 1047890

Showing the first eight; more decompositions exist.
