Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464528, here are decompositions:

19 + 31464509 = 31464528
47 + 31464481 = 31464528
89 + 31464439 = 31464528
101 + 31464427 = 31464528
107 + 31464421 = 31464528
127 + 31464401 = 31464528
131 + 31464397 = 31464528
257 + 31464271 = 31464528

Showing the first eight; more decompositions exist.
