Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492120, here are decompositions:

97 + 2147492023 = 2147492120
223 + 2147491897 = 2147492120
283 + 2147491837 = 2147492120
421 + 2147491699 = 2147492120
523 + 2147491597 = 2147492120
547 + 2147491573 = 2147492120
577 + 2147491543 = 2147492120
643 + 2147491477 = 2147492120

Showing the first eight; more decompositions exist.
