Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530846, here are decompositions:

5 + 31530841 = 31530846
13 + 31530833 = 31530846
19 + 31530827 = 31530846
47 + 31530799 = 31530846
73 + 31530773 = 31530846
163 + 31530683 = 31530846
167 + 31530679 = 31530846
197 + 31530649 = 31530846

Showing the first eight; more decompositions exist.
