Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456554, here are decompositions:

7 + 31456547 = 31456554
23 + 31456531 = 31456554
37 + 31456517 = 31456554
53 + 31456501 = 31456554
67 + 31456487 = 31456554
113 + 31456441 = 31456554
193 + 31456361 = 31456554
223 + 31456331 = 31456554

Showing the first eight; more decompositions exist.
