Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80288, here are decompositions:
- 37 + 80251 = 80288
- 67 + 80221 = 80288
- 79 + 80209 = 80288
- 97 + 80191 = 80288
- 139 + 80149 = 80288
- 181 + 80107 = 80288
- 211 + 80077 = 80288
- 349 + 79939 = 80288
Showing the first eight; more decompositions exist.
