Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80126, here are decompositions:
- 19 + 80107 = 80126
- 127 + 79999 = 80126
- 139 + 79987 = 80126
- 223 + 79903 = 80126
- 283 + 79843 = 80126
- 313 + 79813 = 80126
- 349 + 79777 = 80126
- 433 + 79693 = 80126
Showing the first eight; more decompositions exist.
