Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142618, here are decompositions:
- 11 + 142607 = 142618
- 17 + 142601 = 142618
- 29 + 142589 = 142618
- 59 + 142559 = 142618
- 71 + 142547 = 142618
- 89 + 142529 = 142618
- 149 + 142469 = 142618
- 191 + 142427 = 142618
Showing the first eight; more decompositions exist.
