Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527434, here are decompositions:

157 + 31527277 = 31527434
181 + 31527253 = 31527434
223 + 31527211 = 31527434
241 + 31527193 = 31527434
277 + 31527157 = 31527434
283 + 31527151 = 31527434
541 + 31526893 = 31527434
571 + 31526863 = 31527434

Showing the first eight; more decompositions exist.
