Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80120, here are decompositions:
- 13 + 80107 = 80120
- 43 + 80077 = 80120
- 181 + 79939 = 80120
- 277 + 79843 = 80120
- 307 + 79813 = 80120
- 421 + 79699 = 80120
- 433 + 79687 = 80120
- 463 + 79657 = 80120
Showing the first eight; more decompositions exist.
