Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981300, here are decompositions:

11 + 981289 = 981300
13 + 981287 = 981300
17 + 981283 = 981300
29 + 981271 = 981300
37 + 981263 = 981300
59 + 981241 = 981300
79 + 981221 = 981300
101 + 981199 = 981300

Showing the first eight; more decompositions exist.
