Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004842, here are decompositions:

173 + 1004669 = 1004842
191 + 1004651 = 1004842
281 + 1004561 = 1004842
359 + 1004483 = 1004842
389 + 1004453 = 1004842
401 + 1004441 = 1004842
479 + 1004363 = 1004842
563 + 1004279 = 1004842

Showing the first eight; more decompositions exist.
