Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80042, here are decompositions:
- 3 + 80039 = 80042
- 43 + 79999 = 80042
- 103 + 79939 = 80042
- 139 + 79903 = 80042
- 181 + 79861 = 80042
- 199 + 79843 = 80042
- 229 + 79813 = 80042
- 241 + 79801 = 80042
Showing the first eight; more decompositions exist.
