Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484558, here are decompositions:

97 + 31484461 = 31484558
109 + 31484449 = 31484558
181 + 31484377 = 31484558
199 + 31484359 = 31484558
241 + 31484317 = 31484558
277 + 31484281 = 31484558
349 + 31484209 = 31484558
379 + 31484179 = 31484558

Showing the first eight; more decompositions exist.
