Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482608, here are decompositions:

97 + 31482511 = 31482608
109 + 31482499 = 31482608
181 + 31482427 = 31482608
271 + 31482337 = 31482608
331 + 31482277 = 31482608
337 + 31482271 = 31482608
379 + 31482229 = 31482608
439 + 31482169 = 31482608

Showing the first eight; more decompositions exist.
