Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141640, here are decompositions:
- 3 + 141637 = 141640
- 11 + 141629 = 141640
- 17 + 141623 = 141640
- 53 + 141587 = 141640
- 89 + 141551 = 141640
- 101 + 141539 = 141640
- 131 + 141509 = 141640
- 179 + 141461 = 141640
Showing the first eight; more decompositions exist.
