Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051580, here are decompositions:

31 + 1051549 = 1051580
37 + 1051543 = 1051580
73 + 1051507 = 1051580
109 + 1051471 = 1051580
157 + 1051423 = 1051580
163 + 1051417 = 1051580
433 + 1051147 = 1051580
499 + 1051081 = 1051580

Showing the first eight; more decompositions exist.
