Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454316, here are decompositions:

53 + 31454263 = 31454316
67 + 31454249 = 31454316
97 + 31454219 = 31454316
167 + 31454149 = 31454316
193 + 31454123 = 31454316
199 + 31454117 = 31454316
233 + 31454083 = 31454316
239 + 31454077 = 31454316

Showing the first eight; more decompositions exist.
