Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533692, here are decompositions:

31 + 31533661 = 31533692
61 + 31533631 = 31533692
79 + 31533613 = 31533692
181 + 31533511 = 31533692
193 + 31533499 = 31533692
241 + 31533451 = 31533692
283 + 31533409 = 31533692
313 + 31533379 = 31533692

Showing the first eight; more decompositions exist.
