Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500742, here are decompositions:

13 + 500729 = 500742
19 + 500723 = 500742
23 + 500719 = 500742
29 + 500713 = 500742
43 + 500699 = 500742
71 + 500671 = 500742
113 + 500629 = 500742
139 + 500603 = 500742

Showing the first eight; more decompositions exist.
