Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489830, here are decompositions:

11 + 2147489819 = 2147489830
113 + 2147489717 = 2147489830
131 + 2147489699 = 2147489830
179 + 2147489651 = 2147489830
191 + 2147489639 = 2147489830
251 + 2147489579 = 2147489830
293 + 2147489537 = 2147489830
347 + 2147489483 = 2147489830

Showing the first eight; more decompositions exist.
