Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490384, here are decompositions:

23 + 2147490361 = 2147490384
41 + 2147490343 = 2147490384
101 + 2147490283 = 2147490384
167 + 2147490217 = 2147490384
223 + 2147490161 = 2147490384
307 + 2147490077 = 2147490384
331 + 2147490053 = 2147490384
373 + 2147490011 = 2147490384

Showing the first eight; more decompositions exist.
