Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484408, here are decompositions:

31 + 31484377 = 31484408
127 + 31484281 = 31484408
199 + 31484209 = 31484408
229 + 31484179 = 31484408
337 + 31484071 = 31484408
349 + 31484059 = 31484408
547 + 31483861 = 31484408
601 + 31483807 = 31484408

Showing the first eight; more decompositions exist.
