Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482378, here are decompositions:

29 + 31482349 = 31482378
41 + 31482337 = 31482378
71 + 31482307 = 31482378
97 + 31482281 = 31482378
101 + 31482277 = 31482378
107 + 31482271 = 31482378
131 + 31482247 = 31482378
149 + 31482229 = 31482378

Showing the first eight; more decompositions exist.
