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.
