Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612318, here are decompositions:

5 + 31612313 = 31612318
11 + 31612307 = 31612318
41 + 31612277 = 31612318
167 + 31612151 = 31612318
197 + 31612121 = 31612318
239 + 31612079 = 31612318
401 + 31611917 = 31612318
449 + 31611869 = 31612318

Showing the first eight; more decompositions exist.
