Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464434, here are decompositions:

7 + 31464427 = 31464434
13 + 31464421 = 31464434
37 + 31464397 = 31464434
163 + 31464271 = 31464434
241 + 31464193 = 31464434
367 + 31464067 = 31464434
373 + 31464061 = 31464434
433 + 31464001 = 31464434

Showing the first eight; more decompositions exist.
