Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484858, here are decompositions:

19 + 31484839 = 31484858
37 + 31484821 = 31484858
61 + 31484797 = 31484858
211 + 31484647 = 31484858
241 + 31484617 = 31484858
397 + 31484461 = 31484858
409 + 31484449 = 31484858
499 + 31484359 = 31484858

Showing the first eight; more decompositions exist.
