Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485700, here are decompositions:

13 + 2147485687 = 2147485700
109 + 2147485591 = 2147485700
127 + 2147485573 = 2147485700
277 + 2147485423 = 2147485700
331 + 2147485369 = 2147485700
433 + 2147485267 = 2147485700
439 + 2147485261 = 2147485700
499 + 2147485201 = 2147485700

Showing the first eight; more decompositions exist.
