Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981234, here are decompositions:

13 + 981221 = 981234
47 + 981187 = 981234
61 + 981173 = 981234
83 + 981151 = 981234
97 + 981137 = 981234
101 + 981133 = 981234
157 + 981077 = 981234
167 + 981067 = 981234

Showing the first eight; more decompositions exist.
