Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484554, here are decompositions:

11 + 31484543 = 31484554
41 + 31484513 = 31484554
137 + 31484417 = 31484554
191 + 31484363 = 31484554
251 + 31484303 = 31484554
317 + 31484237 = 31484554
347 + 31484207 = 31484554
461 + 31484093 = 31484554

Showing the first eight; more decompositions exist.
