Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981722, here are decompositions:

19 + 981703 = 981722
31 + 981691 = 981722
199 + 981523 = 981722
229 + 981493 = 981722
241 + 981481 = 981722
271 + 981451 = 981722
283 + 981439 = 981722
331 + 981391 = 981722

Showing the first eight; more decompositions exist.
