Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492018, here are decompositions:

181 + 2147491837 = 2147492018
409 + 2147491609 = 2147492018
421 + 2147491597 = 2147492018
541 + 2147491477 = 2147492018
601 + 2147491417 = 2147492018
757 + 2147491261 = 2147492018
769 + 2147491249 = 2147492018
907 + 2147491111 = 2147492018

Showing the first eight; more decompositions exist.
