Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466852, here are decompositions:

3 + 31466849 = 31466852
31 + 31466821 = 31466852
61 + 31466791 = 31466852
103 + 31466749 = 31466852
139 + 31466713 = 31466852
163 + 31466689 = 31466852
181 + 31466671 = 31466852
223 + 31466629 = 31466852

Showing the first eight; more decompositions exist.
