Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490580, here are decompositions:

3 + 2147490577 = 2147490580
23 + 2147490557 = 2147490580
41 + 2147490539 = 2147490580
167 + 2147490413 = 2147490580
317 + 2147490263 = 2147490580
419 + 2147490161 = 2147490580
491 + 2147490089 = 2147490580
503 + 2147490077 = 2147490580

Showing the first eight; more decompositions exist.
