Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473654, here are decompositions:

101 + 2147473553 = 2147473654
167 + 2147473487 = 2147473654
281 + 2147473373 = 2147473654
353 + 2147473301 = 2147473654
467 + 2147473187 = 2147473654
503 + 2147473151 = 2147473654
593 + 2147473061 = 2147473654
761 + 2147472893 = 2147473654

Showing the first eight; more decompositions exist.
