Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534010, here are decompositions:

31 + 31533979 = 31534010
43 + 31533967 = 31534010
61 + 31533949 = 31534010
139 + 31533871 = 31534010
163 + 31533847 = 31534010
181 + 31533829 = 31534010
241 + 31533769 = 31534010
349 + 31533661 = 31534010

Showing the first eight; more decompositions exist.
