Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80142, here are decompositions:
- 31 + 80111 = 80142
- 71 + 80071 = 80142
- 103 + 80039 = 80142
- 163 + 79979 = 80142
- 199 + 79943 = 80142
- 239 + 79903 = 80142
- 241 + 79901 = 80142
- 269 + 79873 = 80142
Showing the first eight; more decompositions exist.
