Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404862, here are decompositions:

3 + 2147404859 = 2147404862
151 + 2147404711 = 2147404862
223 + 2147404639 = 2147404862
241 + 2147404621 = 2147404862
283 + 2147404579 = 2147404862
373 + 2147404489 = 2147404862
433 + 2147404429 = 2147404862
619 + 2147404243 = 2147404862

Showing the first eight; more decompositions exist.
