Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472646, here are decompositions:

3 + 472643 = 472646
7 + 472639 = 472646
73 + 472573 = 472646
103 + 472543 = 472646
277 + 472369 = 472646
313 + 472333 = 472646
337 + 472309 = 472646
373 + 472273 = 472646

Showing the first eight; more decompositions exist.
