Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580646, here are decompositions:

7 + 580639 = 580646
13 + 580633 = 580646
19 + 580627 = 580646
97 + 580549 = 580646
229 + 580417 = 580646
307 + 580339 = 580646
433 + 580213 = 580646
463 + 580183 = 580646

Showing the first eight; more decompositions exist.
