Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049780, here are decompositions:

7 + 1049773 = 1049780
73 + 1049707 = 1049780
97 + 1049683 = 1049780
103 + 1049677 = 1049780
157 + 1049623 = 1049780
181 + 1049599 = 1049780
211 + 1049569 = 1049780
271 + 1049509 = 1049780

Showing the first eight; more decompositions exist.
