Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464338, here are decompositions:

67 + 31464271 = 31464338
151 + 31464187 = 31464338
271 + 31464067 = 31464338
277 + 31464061 = 31464338
307 + 31464031 = 31464338
337 + 31464001 = 31464338
379 + 31463959 = 31464338
397 + 31463941 = 31464338

Showing the first eight; more decompositions exist.
