Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492730, here are decompositions:

29 + 2147492701 = 2147492730
59 + 2147492671 = 2147492730
109 + 2147492621 = 2147492730
139 + 2147492591 = 2147492730
179 + 2147492551 = 2147492730
191 + 2147492539 = 2147492730
197 + 2147492533 = 2147492730
239 + 2147492491 = 2147492730

Showing the first eight; more decompositions exist.
