Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482498, here are decompositions:

59 + 31482439 = 31482498
71 + 31482427 = 31482498
97 + 31482401 = 31482498
109 + 31482389 = 31482498
149 + 31482349 = 31482498
191 + 31482307 = 31482498
227 + 31482271 = 31482498
241 + 31482257 = 31482498

Showing the first eight; more decompositions exist.
