Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77020, here are decompositions:
- 3 + 77017 = 77020
- 17 + 77003 = 77020
- 29 + 76991 = 77020
- 59 + 76961 = 77020
- 71 + 76949 = 77020
- 101 + 76919 = 77020
- 107 + 76913 = 77020
- 113 + 76907 = 77020
Showing the first eight; more decompositions exist.
