Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012886, here are decompositions:

97 + 1012789 = 1012886
223 + 1012663 = 1012886
229 + 1012657 = 1012886
313 + 1012573 = 1012886
337 + 1012549 = 1012886
367 + 1012519 = 1012886
373 + 1012513 = 1012886
379 + 1012507 = 1012886

Showing the first eight; more decompositions exist.
