Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981932, here are decompositions:

13 + 981919 = 981932
19 + 981913 = 981932
43 + 981889 = 981932
109 + 981823 = 981932
163 + 981769 = 981932
229 + 981703 = 981932
241 + 981691 = 981932
331 + 981601 = 981932

Showing the first eight; more decompositions exist.
