Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513742, here are decompositions:

3 + 513739 = 513742
11 + 513731 = 513742
23 + 513719 = 513742
59 + 513683 = 513742
101 + 513641 = 513742
149 + 513593 = 513742
233 + 513509 = 513742
263 + 513479 = 513742

Showing the first eight; more decompositions exist.
