Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482486, here are decompositions:

47 + 31482439 = 31482486
59 + 31482427 = 31482486
97 + 31482389 = 31482486
137 + 31482349 = 31482486
149 + 31482337 = 31482486
179 + 31482307 = 31482486
193 + 31482293 = 31482486
229 + 31482257 = 31482486

Showing the first eight; more decompositions exist.
