Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490398, here are decompositions:

37 + 2147490361 = 2147490398
181 + 2147490217 = 2147490398
337 + 2147490061 = 2147490398
457 + 2147489941 = 2147490398
499 + 2147489899 = 2147490398
577 + 2147489821 = 2147490398
601 + 2147489797 = 2147490398
811 + 2147489587 = 2147490398

Showing the first eight; more decompositions exist.
