Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490278, here are decompositions:

61 + 2147490217 = 2147490278
331 + 2147489947 = 2147490278
337 + 2147489941 = 2147490278
379 + 2147489899 = 2147490278
457 + 2147489821 = 2147490278
691 + 2147489587 = 2147490278
877 + 2147489401 = 2147490278
1201 + 2147489077 = 2147490278

Showing the first eight; more decompositions exist.
