Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482446, here are decompositions:

7 + 31482439 = 31482446
19 + 31482427 = 31482446
97 + 31482349 = 31482446
103 + 31482343 = 31482446
109 + 31482337 = 31482446
139 + 31482307 = 31482446
199 + 31482247 = 31482446
277 + 31482169 = 31482446

Showing the first eight; more decompositions exist.
