Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492380, here are decompositions:

41 + 2147492339 = 2147492380
53 + 2147492327 = 2147492380
83 + 2147492297 = 2147492380
149 + 2147492231 = 2147492380
197 + 2147492183 = 2147492380
311 + 2147492069 = 2147492380
419 + 2147491961 = 2147492380
443 + 2147491937 = 2147492380

Showing the first eight; more decompositions exist.
