Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464378, here are decompositions:

19 + 31464359 = 31464378
37 + 31464341 = 31464378
97 + 31464281 = 31464378
107 + 31464271 = 31464378
109 + 31464269 = 31464378
191 + 31464187 = 31464378
229 + 31464149 = 31464378
241 + 31464137 = 31464378

Showing the first eight; more decompositions exist.
