Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464128, here are decompositions:

61 + 31464067 = 31464128
67 + 31464061 = 31464128
97 + 31464031 = 31464128
127 + 31464001 = 31464128
271 + 31463857 = 31464128
331 + 31463797 = 31464128
349 + 31463779 = 31464128
439 + 31463689 = 31464128

Showing the first eight; more decompositions exist.
