Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530932, here are decompositions:

31 + 31530901 = 31530932
229 + 31530703 = 31530932
271 + 31530661 = 31530932
283 + 31530649 = 31530932
409 + 31530523 = 31530932
523 + 31530409 = 31530932
541 + 31530391 = 31530932
751 + 31530181 = 31530932

Showing the first eight; more decompositions exist.
