Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947648, here are decompositions:

7 + 947641 = 947648
109 + 947539 = 947648
139 + 947509 = 947648
199 + 947449 = 947648
241 + 947407 = 947648
271 + 947377 = 947648
307 + 947341 = 947648
349 + 947299 = 947648

Showing the first eight; more decompositions exist.
