Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142632, here are decompositions:
- 13 + 142619 = 142632
- 23 + 142609 = 142632
- 31 + 142601 = 142632
- 41 + 142591 = 142632
- 43 + 142589 = 142632
- 59 + 142573 = 142632
- 73 + 142559 = 142632
- 79 + 142553 = 142632
Showing the first eight; more decompositions exist.
