Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464506, here are decompositions:

13 + 31464493 = 31464506
43 + 31464463 = 31464506
67 + 31464439 = 31464506
79 + 31464427 = 31464506
97 + 31464409 = 31464506
109 + 31464397 = 31464506
313 + 31464193 = 31464506
439 + 31464067 = 31464506

Showing the first eight; more decompositions exist.
