Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485654, here are decompositions:

5 + 2147485649 = 2147485654
107 + 2147485547 = 2147485654
131 + 2147485523 = 2147485654
137 + 2147485517 = 2147485654
233 + 2147485421 = 2147485654
311 + 2147485343 = 2147485654
317 + 2147485337 = 2147485654
401 + 2147485253 = 2147485654

Showing the first eight; more decompositions exist.
