Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491478, here are decompositions:

61 + 2147491417 = 2147491478
109 + 2147491369 = 2147491478
229 + 2147491249 = 2147491478
241 + 2147491237 = 2147491478
277 + 2147491201 = 2147491478
367 + 2147491111 = 2147491478
397 + 2147491081 = 2147491478
409 + 2147491069 = 2147491478

Showing the first eight; more decompositions exist.
