Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468542, here are decompositions:

5 + 2147468537 = 2147468542
113 + 2147468429 = 2147468542
251 + 2147468291 = 2147468542
293 + 2147468249 = 2147468542
311 + 2147468231 = 2147468542
353 + 2147468189 = 2147468542
773 + 2147467769 = 2147468542
809 + 2147467733 = 2147468542

Showing the first eight; more decompositions exist.
