Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001894, here are decompositions:

73 + 1001821 = 1001894
97 + 1001797 = 1001894
151 + 1001743 = 1001894
181 + 1001713 = 1001894
211 + 1001683 = 1001894
307 + 1001587 = 1001894
331 + 1001563 = 1001894
367 + 1001527 = 1001894

Showing the first eight; more decompositions exist.
