Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045886, here are decompositions:

67 + 1045819 = 1045886
157 + 1045729 = 1045886
223 + 1045663 = 1045886
313 + 1045573 = 1045886
337 + 1045549 = 1045886
379 + 1045507 = 1045886
463 + 1045423 = 1045886
577 + 1045309 = 1045886

Showing the first eight; more decompositions exist.
