Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80242, here are decompositions:
- 3 + 80239 = 80242
- 11 + 80231 = 80242
- 89 + 80153 = 80242
- 101 + 80141 = 80242
- 131 + 80111 = 80242
- 191 + 80051 = 80242
- 263 + 79979 = 80242
- 269 + 79973 = 80242
Showing the first eight; more decompositions exist.
