Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532300, here are decompositions:

31 + 31532269 = 31532300
73 + 31532227 = 31532300
97 + 31532203 = 31532300
211 + 31532089 = 31532300
229 + 31532071 = 31532300
379 + 31531921 = 31532300
487 + 31531813 = 31532300
661 + 31531639 = 31532300

Showing the first eight; more decompositions exist.
