Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001798, here are decompositions:

139 + 1001659 = 1001798
211 + 1001587 = 1001798
229 + 1001569 = 1001798
271 + 1001527 = 1001798
307 + 1001491 = 1001798
331 + 1001467 = 1001798
367 + 1001431 = 1001798
397 + 1001401 = 1001798

Showing the first eight; more decompositions exist.
