Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008842, here are decompositions:

13 + 1008829 = 1008842
61 + 1008781 = 1008842
229 + 1008613 = 1008842
271 + 1008571 = 1008842
349 + 1008493 = 1008842
409 + 1008433 = 1008842
421 + 1008421 = 1008842
433 + 1008409 = 1008842

Showing the first eight; more decompositions exist.
