Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499284, here are decompositions:

3 + 2147499281 = 2147499284
31 + 2147499253 = 2147499284
43 + 2147499241 = 2147499284
67 + 2147499217 = 2147499284
193 + 2147499091 = 2147499284
331 + 2147498953 = 2147499284
367 + 2147498917 = 2147499284
373 + 2147498911 = 2147499284

Showing the first eight; more decompositions exist.
