Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615852, here are decompositions:

3 + 31615849 = 31615852
5 + 31615847 = 31615852
89 + 31615763 = 31615852
263 + 31615589 = 31615852
269 + 31615583 = 31615852
449 + 31615403 = 31615852
461 + 31615391 = 31615852
509 + 31615343 = 31615852

Showing the first eight; more decompositions exist.
