Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464340, here are decompositions:

59 + 31464281 = 31464340
71 + 31464269 = 31464340
107 + 31464233 = 31464340
191 + 31464149 = 31464340
197 + 31464143 = 31464340
293 + 31464047 = 31464340
419 + 31463921 = 31464340
431 + 31463909 = 31464340

Showing the first eight; more decompositions exist.
