Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77554, here are decompositions:
- 3 + 77551 = 77554
- 5 + 77549 = 77554
- 11 + 77543 = 77554
- 41 + 77513 = 77554
- 83 + 77471 = 77554
- 107 + 77447 = 77554
- 137 + 77417 = 77554
- 263 + 77291 = 77554
Showing the first eight; more decompositions exist.
