Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498278, here are decompositions:

89 + 2147498189 = 2147498278
131 + 2147498147 = 2147498278
137 + 2147498141 = 2147498278
389 + 2147497889 = 2147498278
509 + 2147497769 = 2147498278
521 + 2147497757 = 2147498278
587 + 2147497691 = 2147498278
617 + 2147497661 = 2147498278

Showing the first eight; more decompositions exist.
