Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482554, here are decompositions:

3 + 31482551 = 31482554
43 + 31482511 = 31482554
127 + 31482427 = 31482554
211 + 31482343 = 31482554
277 + 31482277 = 31482554
283 + 31482271 = 31482554
307 + 31482247 = 31482554
457 + 31482097 = 31482554

Showing the first eight; more decompositions exist.
