Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041842, here are decompositions:

13 + 1041829 = 1041842
19 + 1041823 = 1041842
199 + 1041643 = 1041842
223 + 1041619 = 1041842
271 + 1041571 = 1041842
283 + 1041559 = 1041842
313 + 1041529 = 1041842
331 + 1041511 = 1041842

Showing the first eight; more decompositions exist.
