Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611256, here are decompositions:

167 + 31611089 = 31611256
227 + 31611029 = 31611256
233 + 31611023 = 31611256
239 + 31611017 = 31611256
389 + 31610867 = 31611256
617 + 31610639 = 31611256
683 + 31610573 = 31611256
863 + 31610393 = 31611256

Showing the first eight; more decompositions exist.
