Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486890, here are decompositions:

11 + 2147486879 = 2147486890
41 + 2147486849 = 2147486890
47 + 2147486843 = 2147486890
71 + 2147486819 = 2147486890
149 + 2147486741 = 2147486890
179 + 2147486711 = 2147486890
359 + 2147486531 = 2147486890
383 + 2147486507 = 2147486890

Showing the first eight; more decompositions exist.
