Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513738, here are decompositions:

7 + 513731 = 513738
11 + 513727 = 513738
19 + 513719 = 513738
41 + 513697 = 513738
47 + 513691 = 513738
59 + 513679 = 513738
89 + 513649 = 513738
97 + 513641 = 513738

Showing the first eight; more decompositions exist.
