Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468828, here are decompositions:

19 + 2147468809 = 2147468828
229 + 2147468599 = 2147468828
331 + 2147468497 = 2147468828
397 + 2147468431 = 2147468828
487 + 2147468341 = 2147468828
709 + 2147468119 = 2147468828
907 + 2147467921 = 2147468828
1069 + 2147467759 = 2147468828

Showing the first eight; more decompositions exist.
