Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485378, here are decompositions:

41 + 2147485337 = 2147485378
131 + 2147485247 = 2147485378
197 + 2147485181 = 2147485378
257 + 2147485121 = 2147485378
281 + 2147485097 = 2147485378
449 + 2147484929 = 2147485378
509 + 2147484869 = 2147485378
557 + 2147484821 = 2147485378

Showing the first eight; more decompositions exist.
