Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539754, here are decompositions:

17 + 31539737 = 31539754
41 + 31539713 = 31539754
47 + 31539707 = 31539754
83 + 31539671 = 31539754
167 + 31539587 = 31539754
353 + 31539401 = 31539754
401 + 31539353 = 31539754
563 + 31539191 = 31539754

Showing the first eight; more decompositions exist.
