Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482452, here are decompositions:

13 + 31482439 = 31482452
103 + 31482349 = 31482452
109 + 31482343 = 31482452
181 + 31482271 = 31482452
223 + 31482229 = 31482452
283 + 31482169 = 31482452
349 + 31482103 = 31482452
409 + 31482043 = 31482452

Showing the first eight; more decompositions exist.
