Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 586440, here are decompositions:

7 + 586433 = 586440
11 + 586429 = 586440
37 + 586403 = 586440
53 + 586387 = 586440
73 + 586367 = 586440
79 + 586361 = 586440
131 + 586309 = 586440
139 + 586301 = 586440

Showing the first eight; more decompositions exist.
