Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606896, here are decompositions:

17 + 31606879 = 31606896
67 + 31606829 = 31606896
193 + 31606703 = 31606896
199 + 31606697 = 31606896
229 + 31606667 = 31606896
239 + 31606657 = 31606896
313 + 31606583 = 31606896
317 + 31606579 = 31606896

Showing the first eight; more decompositions exist.
