Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499278, here are decompositions:

37 + 2147499241 = 2147499278
61 + 2147499217 = 2147499278
139 + 2147499139 = 2147499278
241 + 2147499037 = 2147499278
367 + 2147498911 = 2147499278
541 + 2147498737 = 2147499278
601 + 2147498677 = 2147499278
619 + 2147498659 = 2147499278

Showing the first eight; more decompositions exist.
