Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485508, here are decompositions:

61 + 2147485447 = 2147485508
97 + 2147485411 = 2147485508
127 + 2147485381 = 2147485508
139 + 2147485369 = 2147485508
151 + 2147485357 = 2147485508
199 + 2147485309 = 2147485508
241 + 2147485267 = 2147485508
307 + 2147485201 = 2147485508

Showing the first eight; more decompositions exist.
