Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051286, here are decompositions:

3 + 1051283 = 1051286
109 + 1051177 = 1051286
139 + 1051147 = 1051286
277 + 1051009 = 1051286
283 + 1051003 = 1051286
337 + 1050949 = 1051286
373 + 1050913 = 1051286
433 + 1050853 = 1051286

Showing the first eight; more decompositions exist.
