Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464318, here are decompositions:

37 + 31464281 = 31464318
47 + 31464271 = 31464318
131 + 31464187 = 31464318
181 + 31464137 = 31464318
239 + 31464079 = 31464318
251 + 31464067 = 31464318
257 + 31464061 = 31464318
271 + 31464047 = 31464318

Showing the first eight; more decompositions exist.
