Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489590, here are decompositions:

3 + 2147489587 = 2147489590
11 + 2147489579 = 2147489590
47 + 2147489543 = 2147489590
53 + 2147489537 = 2147489590
107 + 2147489483 = 2147489590
149 + 2147489441 = 2147489590
167 + 2147489423 = 2147489590
293 + 2147489297 = 2147489590

Showing the first eight; more decompositions exist.
