Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484958, here are decompositions:

17 + 31484941 = 31484958
47 + 31484911 = 31484958
137 + 31484821 = 31484958
157 + 31484801 = 31484958
181 + 31484777 = 31484958
311 + 31484647 = 31484958
331 + 31484627 = 31484958
389 + 31484569 = 31484958

Showing the first eight; more decompositions exist.
