Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001778, here are decompositions:

109 + 1001669 = 1001778
139 + 1001639 = 1001778
149 + 1001629 = 1001778
157 + 1001621 = 1001778
191 + 1001587 = 1001778
227 + 1001551 = 1001778
229 + 1001549 = 1001778
251 + 1001527 = 1001778

Showing the first eight; more decompositions exist.
