Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051550, here are decompositions:

7 + 1051543 = 1051550
43 + 1051507 = 1051550
79 + 1051471 = 1051550
127 + 1051423 = 1051550
373 + 1051177 = 1051550
397 + 1051153 = 1051550
499 + 1051051 = 1051550
523 + 1051027 = 1051550

Showing the first eight; more decompositions exist.
