Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142702, here are decompositions:
- 3 + 142699 = 142702
- 5 + 142697 = 142702
- 29 + 142673 = 142702
- 83 + 142619 = 142702
- 101 + 142601 = 142702
- 113 + 142589 = 142702
- 149 + 142553 = 142702
- 173 + 142529 = 142702
Showing the first eight; more decompositions exist.
