Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464324, here are decompositions:

43 + 31464281 = 31464324
53 + 31464271 = 31464324
131 + 31464193 = 31464324
137 + 31464187 = 31464324
181 + 31464143 = 31464324
257 + 31464067 = 31464324
263 + 31464061 = 31464324
277 + 31464047 = 31464324

Showing the first eight; more decompositions exist.
