Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464548, here are decompositions:

67 + 31464481 = 31464548
97 + 31464451 = 31464548
109 + 31464439 = 31464548
127 + 31464421 = 31464548
139 + 31464409 = 31464548
151 + 31464397 = 31464548
277 + 31464271 = 31464548
487 + 31464061 = 31464548

Showing the first eight; more decompositions exist.
