Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510742, here are decompositions:

59 + 510683 = 510742
131 + 510611 = 510742
173 + 510569 = 510742
191 + 510551 = 510742
293 + 510449 = 510742
359 + 510383 = 510742
431 + 510311 = 510742
443 + 510299 = 510742

Showing the first eight; more decompositions exist.
