Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80140, here are decompositions:
- 29 + 80111 = 80140
- 89 + 80051 = 80140
- 101 + 80039 = 80140
- 167 + 79973 = 80140
- 173 + 79967 = 80140
- 197 + 79943 = 80140
- 233 + 79907 = 80140
- 239 + 79901 = 80140
Showing the first eight; more decompositions exist.
