Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61742, here are decompositions:

13 + 61729 = 61742
19 + 61723 = 61742
61 + 61681 = 61742
139 + 61603 = 61742
181 + 61561 = 61742
199 + 61543 = 61742
223 + 61519 = 61742
271 + 61471 = 61742

Showing the first eight; more decompositions exist.
