Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74520, here are decompositions:
- 11 + 74509 = 74520
- 13 + 74507 = 74520
- 31 + 74489 = 74520
- 67 + 74453 = 74520
- 71 + 74449 = 74520
- 79 + 74441 = 74520
- 101 + 74419 = 74520
- 107 + 74413 = 74520
Showing the first eight; more decompositions exist.
