Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74478, here are decompositions:
- 7 + 74471 = 74478
- 29 + 74449 = 74478
- 37 + 74441 = 74478
- 59 + 74419 = 74478
- 67 + 74411 = 74478
- 97 + 74381 = 74478
- 101 + 74377 = 74478
- 167 + 74311 = 74478
Showing the first eight; more decompositions exist.
