Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055818, here are decompositions:

17 + 1055801 = 1055818
47 + 1055771 = 1055818
227 + 1055591 = 1055818
251 + 1055567 = 1055818
317 + 1055501 = 1055818
347 + 1055471 = 1055818
389 + 1055429 = 1055818
419 + 1055399 = 1055818

Showing the first eight; more decompositions exist.
