Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981846, here are decompositions:

23 + 981823 = 981846
29 + 981817 = 981846
37 + 981809 = 981846
139 + 981707 = 981846
149 + 981697 = 981846
163 + 981683 = 981846
193 + 981653 = 981846
223 + 981623 = 981846

Showing the first eight; more decompositions exist.
