Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142656, here are decompositions:
- 37 + 142619 = 142656
- 47 + 142609 = 142656
- 67 + 142589 = 142656
- 83 + 142573 = 142656
- 89 + 142567 = 142656
- 97 + 142559 = 142656
- 103 + 142553 = 142656
- 109 + 142547 = 142656
Showing the first eight; more decompositions exist.
