Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501680, here are decompositions:

43 + 501637 = 501680
79 + 501601 = 501680
103 + 501577 = 501680
229 + 501451 = 501680
271 + 501409 = 501680
313 + 501367 = 501680
337 + 501343 = 501680
409 + 501271 = 501680

Showing the first eight; more decompositions exist.
