Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527932, here are decompositions:

19 + 31527913 = 31527932
103 + 31527829 = 31527932
151 + 31527781 = 31527932
223 + 31527709 = 31527932
229 + 31527703 = 31527932
349 + 31527583 = 31527932
409 + 31527523 = 31527932
433 + 31527499 = 31527932

Showing the first eight; more decompositions exist.
