Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465338, here are decompositions:

17 + 31465321 = 31465338
29 + 31465309 = 31465338
227 + 31465111 = 31465338
239 + 31465099 = 31465338
269 + 31465069 = 31465338
277 + 31465061 = 31465338
347 + 31464991 = 31465338
397 + 31464941 = 31465338

Showing the first eight; more decompositions exist.
