Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564698, here are decompositions:

29 + 31564669 = 31564698
37 + 31564661 = 31564698
41 + 31564657 = 31564698
59 + 31564639 = 31564698
107 + 31564591 = 31564698
167 + 31564531 = 31564698
181 + 31564517 = 31564698
197 + 31564501 = 31564698

Showing the first eight; more decompositions exist.
