Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77444, here are decompositions:
- 13 + 77431 = 77444
- 61 + 77383 = 77444
- 67 + 77377 = 77444
- 97 + 77347 = 77444
- 127 + 77317 = 77444
- 181 + 77263 = 77444
- 277 + 77167 = 77444
- 307 + 77137 = 77444
Showing the first eight; more decompositions exist.
