Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981962, here are decompositions:

13 + 981949 = 981962
43 + 981919 = 981962
73 + 981889 = 981962
139 + 981823 = 981962
151 + 981811 = 981962
193 + 981769 = 981962
271 + 981691 = 981962
439 + 981523 = 981962

Showing the first eight; more decompositions exist.
