Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482908, here are decompositions:

19 + 31482889 = 31482908
109 + 31482799 = 31482908
199 + 31482709 = 31482908
241 + 31482667 = 31482908
277 + 31482631 = 31482908
349 + 31482559 = 31482908
397 + 31482511 = 31482908
409 + 31482499 = 31482908

Showing the first eight; more decompositions exist.
