Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493140, here are decompositions:

31 + 2147493109 = 2147493140
61 + 2147493079 = 2147493140
97 + 2147493043 = 2147493140
103 + 2147493037 = 2147493140
139 + 2147493001 = 2147493140
181 + 2147492959 = 2147493140
211 + 2147492929 = 2147493140
439 + 2147492701 = 2147493140

Showing the first eight; more decompositions exist.
