Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404886, here are decompositions:

307 + 2147404579 = 2147404886
397 + 2147404489 = 2147404886
439 + 2147404447 = 2147404886
457 + 2147404429 = 2147404886
577 + 2147404309 = 2147404886
643 + 2147404243 = 2147404886
733 + 2147404153 = 2147404886
787 + 2147404099 = 2147404886

Showing the first eight; more decompositions exist.
