Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489770, here are decompositions:

53 + 2147489717 = 2147489770
71 + 2147489699 = 2147489770
131 + 2147489639 = 2147489770
191 + 2147489579 = 2147489770
227 + 2147489543 = 2147489770
233 + 2147489537 = 2147489770
347 + 2147489423 = 2147489770
479 + 2147489291 = 2147489770

Showing the first eight; more decompositions exist.
