Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491430, here are decompositions:

13 + 2147491417 = 2147491430
61 + 2147491369 = 2147491430
157 + 2147491273 = 2147491430
181 + 2147491249 = 2147491430
193 + 2147491237 = 2147491430
211 + 2147491219 = 2147491430
229 + 2147491201 = 2147491430
307 + 2147491123 = 2147491430

Showing the first eight; more decompositions exist.
