Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464370, here are decompositions:

11 + 31464359 = 31464370
29 + 31464341 = 31464370
89 + 31464281 = 31464370
101 + 31464269 = 31464370
137 + 31464233 = 31464370
227 + 31464143 = 31464370
233 + 31464137 = 31464370
449 + 31463921 = 31464370

Showing the first eight; more decompositions exist.
