Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490138, here are decompositions:

29 + 2147490109 = 2147490138
61 + 2147490077 = 2147490138
127 + 2147490011 = 2147490138
181 + 2147489957 = 2147490138
191 + 2147489947 = 2147490138
197 + 2147489941 = 2147490138
229 + 2147489909 = 2147490138
239 + 2147489899 = 2147490138

Showing the first eight; more decompositions exist.
