Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981944, here are decompositions:

3 + 981941 = 981944
31 + 981913 = 981944
127 + 981817 = 981944
241 + 981703 = 981944
307 + 981637 = 981944
367 + 981577 = 981944
421 + 981523 = 981944
463 + 981481 = 981944

Showing the first eight; more decompositions exist.
