Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464500, here are decompositions:

7 + 31464493 = 31464500
19 + 31464481 = 31464500
37 + 31464463 = 31464500
61 + 31464439 = 31464500
73 + 31464427 = 31464500
79 + 31464421 = 31464500
103 + 31464397 = 31464500
229 + 31464271 = 31464500

Showing the first eight; more decompositions exist.
