Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529274, here are decompositions:

5 + 31529269 = 31529274
17 + 31529257 = 31529274
31 + 31529243 = 31529274
61 + 31529213 = 31529274
107 + 31529167 = 31529274
167 + 31529107 = 31529274
193 + 31529081 = 31529274
277 + 31528997 = 31529274

Showing the first eight; more decompositions exist.
