Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464420, here are decompositions:

11 + 31464409 = 31464420
19 + 31464401 = 31464420
23 + 31464397 = 31464420
61 + 31464359 = 31464420
79 + 31464341 = 31464420
139 + 31464281 = 31464420
149 + 31464271 = 31464420
151 + 31464269 = 31464420

Showing the first eight; more decompositions exist.
