Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484258, here are decompositions:

19 + 31484239 = 31484258
79 + 31484179 = 31484258
97 + 31484161 = 31484258
199 + 31484059 = 31484258
277 + 31483981 = 31484258
331 + 31483927 = 31484258
397 + 31483861 = 31484258
439 + 31483819 = 31484258

Showing the first eight; more decompositions exist.
