Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489858, here are decompositions:

37 + 2147489821 = 2147489858
61 + 2147489797 = 2147489858
271 + 2147489587 = 2147489858
421 + 2147489437 = 2147489858
457 + 2147489401 = 2147489858
769 + 2147489089 = 2147489858
991 + 2147488867 = 2147489858
1117 + 2147488741 = 2147489858

Showing the first eight; more decompositions exist.
