Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142102, here are decompositions:
- 3 + 142099 = 142102
- 5 + 142097 = 142102
- 41 + 142061 = 142102
- 53 + 142049 = 142102
- 71 + 142031 = 142102
- 83 + 142019 = 142102
- 131 + 141971 = 142102
- 239 + 141863 = 142102
Showing the first eight; more decompositions exist.
