Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464554, here are decompositions:

7 + 31464547 = 31464554
61 + 31464493 = 31464554
73 + 31464481 = 31464554
103 + 31464451 = 31464554
127 + 31464427 = 31464554
157 + 31464397 = 31464554
283 + 31464271 = 31464554
367 + 31464187 = 31464554

Showing the first eight; more decompositions exist.
