Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486818, here are decompositions:

107 + 2147486711 = 2147486818
149 + 2147486669 = 2147486818
311 + 2147486507 = 2147486818
317 + 2147486501 = 2147486818
359 + 2147486459 = 2147486818
419 + 2147486399 = 2147486818
431 + 2147486387 = 2147486818
479 + 2147486339 = 2147486818

Showing the first eight; more decompositions exist.
