Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482506, here are decompositions:

7 + 31482499 = 31482506
67 + 31482439 = 31482506
79 + 31482427 = 31482506
157 + 31482349 = 31482506
163 + 31482343 = 31482506
199 + 31482307 = 31482506
229 + 31482277 = 31482506
277 + 31482229 = 31482506

Showing the first eight; more decompositions exist.
